В HSR, Dr. Ratio, being a legendary character of the Path of the Hunt, plays the role of main damage dealer, and the main damage is done by bonus attacks, which have an initial activation chance of 40%. The percentage, in turn, increases with the number of negative statuses on the enemy target selected for attack. Despite the fact that the hero has the ability to impose debuff on opponents through the technique and the hidden talent "Inference", in reality, for effective roleplaying, other representatives with the described mechanics in the team are extremely important to him.
For this reason, teams that are built around this imaginary unit concentrate several characters that can maintain negative effects. These can include heroes of both Nihility and other Paths - be it The Hunt, Abundance, Preservation, and others. As a result, Veritas can be called "forgiving" in terms of group selection, but he still needs third-party investments through equipment in order to deal acceptable damage and show good results in the process of passing high-level content.

Hero's story
Veritas is a scholar from the Intelligentsia Guild, whose research often causes controversy. He is quite a famous figure in social circles. On the man's home planet, there are at least eight documentaries telling about his legendary deeds, as well as more than ten memoirs, some of which touch on the scientist's personal biography. Opinions about the man, in turn, can be both negative and positive, but it is unlikely that there will be anyone who will decide to argue with the statement "Dr. Ratio is a significant figure in the world of scientists", because his works are overwhelmingly impressive.
It is known that Veritas is the first person in the last two amber eras to be awarded the highest student degree by the Veritas Prime Academy in recognition of his outstanding achievements in the fields of biology, medicine, natural theology, philosophy, mathematics, physics and technology. This award is an unimaginable sensation, and many are ready to respect the man at least for this.
Among other things, there are still rumors among scientists that in the distant past Veritas tried to join The Genius Society, but Nous never looked in his direction, despite the baggage of discoveries and research works that he brought to the world of people. One way or another, this story is still discussed from time to time by the highest minds, and many sympathize with the doctor. According to some, the inability of the "Society" to recognize the merits of Ratio is a manifestation of the limitations of geniuses.

Features
The basic stats that increase with the leveling and ascension of the scientist are health, defense, and attack power. Speed and taunt are the only stats that do not change with leveling. The exact values of each stat depending on the lvl are presented in the table:
| Level | Health | ATK | DEF | Speed | Taunt |
| 1 | 142 | 105 | 62 | 103 | 75 |
| 10 | 206 | 153 | 90 | 103 | 75 |

How skills work
The hero is a representative of the Hunt, that is, his main skills are aimed at inflicting damage on single targets. Character's damage element is imaginary. The main feature is his talent that affects the activation of powerful bonus attacks. The chance, in turn, directly depends on the number of negative statuses affecting the enemy. Initially, the chance is 40%, each negative effect increases it by 20%.
In general, the team's gameplay is entirely focused on the mechanics described. Veritas' direct strikes are effective, but he makes the greatest contribution to the battle directly with additional strikes provoked by the talent. As a result, despite the fact that the scientist is able to maintain debuff on enemy targets through the technique and the "Deduction" trace, he achieves greater effectiveness in cooperation with other units that are also able to impose negative statuses.
Active skills
Mold of Idolatry Technique || Debuff
Using the technique creates a special space that attracts attacks from nearby enemies for 10 seconds. If combat with an enemy begins in this space, there is a base chance of 100% to reduce the speed of each opponent by 15% for 2 turns.
Creates a space within which enemies receive the negative effect "Taunt". Activating combat in this space causes enemies' speed to be reduced for the next 2 turns. An important point: only one space created by allies can exist at a time, that is, the scientist’s technique is incompatible, for example, with the technique of Fire Himeko Incomplete Combustion.
Basic Attack Mind is Might || Single Attack
Deals imaginary damage to the selected enemy equal to 50-140% of ATK.
Deals a small % of imaginary damage to the selected enemy. It is not the main source of DPS for the character, but can be used if there are no “free” skill points to carry out a more powerful attack.
Skill "Intellectual Midwifery" || Single Attack
Deals imaginary damage to the selected enemy equal to 75-187.5% of ATK.
Deals a large % of imaginary damage to the selected enemy. Helps activate the bonus attack described in the talent.
Super Ability "Syllogistic Paradox" || Single Attack
Deals imaginary damage to the selected enemy equal to 144-288% of ATK, and places the "Wiseman's Folly" status on them. When the hero's ally attacks an enemy with this status, the character carries out 1 bonus attack on this target, as described in his talent.
The Wiseman's Folly status can be activated up to 2 times, and it only affects the last target of the ult. Using the ultimate skill, in turn, resets the number of available activations of this effect.
Deals a large % of Imaginary damage to a target enemy and is the source of the Wiseman's Folly debuff, which activates the Doctor's bonus attack after an ally hits that enemy.
Passive Skills
Talent "Cogito, Ergo Sum" || Single attack
Using a skill has a fixed 40% chance of performing a bonus attack on the target, which deals imaginary damage equal to 135-337.5% of attack power. For each debuff the target has, the chance is increased by 20%. If the target is defeated before the bonus attack is activated, the bonus attack will be directed at a random enemy.
Activating the skill has a chance to perform a bonus attack on the target. The initial chance is 40%, the presence of negative effects on the enemy increases this chance by 20% (max. 100%).
Leveling Order
Talent/Skill ≥ ult > basic attack
The hero's main sources of damage are the bonus attack from the talent "Cogito, Ergo Sum", skill "Intellectual Midwifery" and ult "Syllogistic Paradox". Therefore, these skills need consistent and priority development. Basic attack is not a priority. It can be improved if there are “free” resources, or after increasing the level of the previously listed abilities.
Traces
All traces:
| Attack Power +4.0% (lvl 1) | |||
| "Summation" (A2): Using the skill increases Crit. Chance by 2.5% and Crit. Damage by 5% for each debuff the target has. This effect can stack up to 6 times. | Crit chance +2.7% (A2) | Attack Power +4.0% (A3) | |
| Defense +5.0% (A3) | |||
| "Inference" (A4): Using a skill to attack an enemy has a base chance of 100% reducing the target's resistance to effects by 10% for 2 turns. | Attack Power +6.0% (A4) | Crit chance +4.0% (A5) | |
| Attack Power +6.0% (A5) | |||
| "Inference" (A6): When the unit deals damage to a target with 3 or more debuffs, damage dealt to that target is increased by 10% for each debuff the target has, up to a maximum of 50%. | Defense +7.5% (A6) | Crit chance +5.3% (lvl 75) | Attack Power +8.0% (lvl 80) |
After learning all the traces, the total increase in characteristics will be:
- attack power - + 28.0 %
- crit chance - + 12.0 %
- defense - + 12.5 %
Eidolons
All consts:
| E1 | Max. the number of levels of the “Summation” status described in the character’s “Traces” increases by 4. At the beginning of the battle, the character immediately receives level 4. “ Summation” status. This effect requires an open Summation Trace to activate. |
| E2 | After the bonus attack described in the character's talent hits the target, it deals additional imaginary damage equal to 20% of the attack power for each debuff the enemy has. This effect can trigger up to 4 times for each bonus attack. |
| E3 |
|
| E4 | When the talent is triggered, it additionally restores 15 energy. |
| E5 |
|
| E6 | Max. the number of triggers of the “Wiseman's Folly” status increases by 1. The damage of the bonus attack described in the talent increases by 50%. |
The best eidolons of Dr. Ratio are the first, second and sixth ones:
- E1 - passively affects the additional increase of such important combat characteristics as crit. chance and crit. damage, through traces. The optimal solution if you plan to pull for duplicates of the character.
- E2 - Increases the damage of the bonus attack described in the talent. The blow is considered the basis of damage, therefore, this acquisition will be extremely useful, since it will boost him in the position of the main damage dealer in the team.
- E6 - another increase in bonus attacks that will be useful for the unit.
As a F2P player, if you plan to pull for additional eidolons, you can stop at the first const. This acquisition will significantly boost Veritas and allow you to complete any high-level content without any problems.
How to play Dr. Ratio
The principle of playing with Veritas in a team is based on the constant maintenance of negative effects on the enemy: the more debuff will affect the enemy, the more often the bonus attack will be activated after using the "Intellectual Midwifery" skill. Fixed chance - 40%. Each negative status, in turn, increases the initial chance by 20%, that is, for the stable operation of the talent "Cogito, Ergo Sum" it is necessary to maintain at least 3 negative debuffs on the enemy.
The ideal support character a the Nihility follower, such as Fire Jiaoqiu. However, if the hero is absent, you can use an equally attractive Ice Pela.
It is the Intelligence Officer and her synergy with the Doctor that will be discussed further to clarify how Veritas' skills and passive talents work. Maintaining at least 3 debuffs during battle on the enemy can be carried out as follows:
- First negative status from the scientist's skill itself - after use with the learnt trace "Inference" reduces resistance to effects by 10% for 2 turns.
- Second negative status from Pela’s ult - after using the ultimate skill, imposes the “Exposed” status on opponents, which reduces the enemy’s defense by 30% for 2 turns.
- Optional: additional negative status from Pela's skill when she has 4 eidolons (after using the skill, it has a base chance of 100% reducing the target's ice resistance by 12% for 2 turns).
- Optional: Additional negative status from the Light Cone of Nihility Resolution Shines As Pearls of Sweat, equipped on Pela - after an attack, imposes the “Ensnared” status on the enemy, which reduces defense by 12% for 1 turn.
It's important to note that the "Wiseman's Folly" from Dr. Ratio's Ultimate does not count as a debuff needed to activate the bonus attack.
Thus, it is possible to achieve constant activation of the bonus attack when fighting single opponents. Additionally, Veritas will receive increases to crit. chance and crit. damage, as well as to the total damage dealt when the " Summation" and "Inference" traces are learnt. The situation will undoubtedly be made easier by auxiliary options - for example, equipping the signature weapon "card" Baptism of Pure Thought or using other support heroes that can apply various debuffs. Pela is considered as an example and solely as an accessible character that is easy to obtain due to her epic affiliation.
Dr. Ratio's Rotation
As for other recommendations, if you play with the scientist in the team - they repeat the advice that is assigned to other representatives of the damage-dealing Paths:
- Before the battle, use the techniques of support heroes. The last action is to activate the technique Mold of Idolatry, and then attack. Thus, at the beginning of the battle, the opponents will receive the negative effect of decreasing speed by 15% for the next 2 turns.
- Activate other abilities of support characters already during the battle, if it is their turn to use the skill. Positive effects from representatives of Harmony (if any), as well as negative statuses from followers of Nihility will significantly boost the main DPS hero aka Veritas.
- Use the skill during the doctor's turn, "Intellectual Midwifery": it deals decent damage and probably activates the talent, performing a powerful bonus attack on the initially selected enemy.
- Once the energy to activate the ultimate skill reaches the maximum, use Syllogistic Paradox, then attack the enemy affected by the status "Wiseman's Folly" with an allied hero. This will allow you to apply another bonus hit.
- As a result, alternate the activation of the skill with the ult.

Strengths and Weaknesses
Having understood how the team's abilities work and having figured out its rotation, we can draw a conclusion about the advantages and disadvantages of the imaginary representative of the Hunt:
| Strengths | Weaknesses |
| High damage against bosses. The main skills are focused on dealing damage to single targets. Thus, the hero becomes an excellent DPS character for high-level missions. "Forgotten Hall" и "Apocalyptic Shadow". | Lack of AoE abilities. Skills lack AoE effects, which makes it take longer to deal with groups of enemies. For clearing certain content, for example, "Pure Fiction" , the scientist needs additional support. |
| Competitiveness. Not inferior to other representatives of the Hunt, as well as the main followers of the Path of Destruction, who occupy high positions in tier lists, thanks to powerful bonus attacks and perfect synergy with the heroes of the Void. | Dependence of bonus attacks on debuffs affecting enemies. The more negative effects affect the enemy, the higher the chance of activating the bonus attack from the talent. To fully implement all the features of the scientist, representatives of Nihility with multiple debuffs must be present in the team with him. |
| Built-in bonuses to significant combat characteristics. Automatically increases significant combat stats (such as critical damage and critical chance) thanks to the "Summation" effect. |
Dr. Ratio's Best Builds in Honkai: Star Rail
Veritas is one of the representatives of the Hunt, which has powerful bonus attacks in its arsenal of skills, capable of inflicting high damage on single targets. The overall DPS depends on attack power of the character, in addition to the named characteristics, the hero needs gains in such indicators as CRIT DMG, CRIT Rate and bonus to imaginary damage. Accordingly, the build of Dr. Ratio in HSR is based on increasing the listed stats.
An important characteristic is speed, which affects the frequency of moves: the more often the scientist can use his skill, the more often the bonus attack from the talent will be activated. Based on what is discussed in the following paragraphs, we will analyze what the unit can be equipped with, given the abundance of suitable light cones and artifacts.
Recommended Stats
The main characteristics that are recommended to look for in cavern relics and planar ornaments:
| Head | HP (fixed) |
| Hands | Attack Power (fixed) |
| Body | crit. damage or crit. chance |
| Boots | Speed |
| Planar Sphere | Bonus imaginary damage (priority) or bonus imaginary damage (alternative) |
| Link Rope | ATK |
The priority of auxiliary, that is, “lower” stats is built on the following basis:
CRIT Rate/DMG > ATK (%) > speed
The optimal final indicators that are recommended to have on the character upon reaching level 80:
- ATK — 2 and more.
- Health — 2 and more.
- Speed — 120+ or 135+ if the following parts of planar ornaments are equipped: Firmament Frontline: Glamoth.
- CRIT Rate — 50%+ (the ideal value is 80-100% precisely within the framework of a battle, where the “Summation” trace is taken into account)
- CRIT DMG — 150%+ (the ideal value is 180-200% precisely within the framework of a battle when working with the “Summation” trace).
Light Cone Rating
When choosing a weapon, it is important to remember that this character belongs to the Path of the Hunt, therefore, the chosen light cone must match his role in the party, otherwise the passive talent of the "card" will not work. Stats to pay attention to:
- Attack Power;
- crit damage and crit chance.
A great addition would be effects aimed at increasing skill damage, ult and/or bonus attack. Among other things, good options include weapon "cards", the passive talents of which help impose additional debuffs on opponents. The ideal solution, in turn, would be Veritas' signature light cone - Baptism of Pure Thought.
| Light cone | Effect | Recommendation |
|---|---|---|
 Baptism of Pure Thought | The owner's crit. damage increases by 20-32%. For each existing debuff the enemy has the owner;s crit. damage inflicted on this target increases by additional 8-12%. This effect can stack up to 3 times. Using a ult to attack a target inflicts the "Disputation" status on the owner, which increases damage dealt by 36-60% and allows the bonus attack to ignore 24-40% of enemy defense. This effect lasts for 2 turns. | Signature light cone, which provides an increase to critical damage, and also increases outgoing damage. An important "plus" is the "Disputation" status, which allows the character and his bonus attacks to ignore a certain % of enemy defense. If you choose between E1 and his weapon "card", then "Baptism of Pure Thought" will be better, since in comparison the number of positive effects offered is many times better. In addition, the light cone acts as a source of additional negative status, affecting the increase in the chance of the scientist to carry out a bonus attack, which can significantly simplify the formation of the team if limited to suitable representatives of Nihility. |
 Worrisome, Blissful | Owner's crit chance is increased by 18-30%, and damage from a bonus attack is reduced 30-50%. After performing a bonus attack, it applies the “Tame” status to the target, which can stack up to 2 times. When an ally hits an enemy with the Tame status, each level of this status increases the crit dealt. damage by 12-20%. | Offers direct increases to damage output from bonus attacks, which is important for Veritas since bonus attacks are considered his primary source of damage. Additionally, it provides a nice boost to crit chance, which can make stat selection easier later on when leveling cavern relics and planar ornaments. A significant "plus" is the "Tame" status, which will additionally increase the damage received by the enemy during the battle. Similar to the signature, the named effect will act as a source of debuff, influencing the increase in the chance of the character to carry out a bonus attack. |
 Swordplay (H5) | When the owner attacks the same enemy multiple times, the damage they deal increases by 8-16%. This effect can stack up to 5 times. This effect is removed when the wearer changes their target. | An epic cone of light that at high Overlay level outperforms most legendary weapon cards. The reason for this is the 80% damage dealt, which is effectively revealed during a fight with a solo target. |
 Cruising in the Stellar Sea (S5) | F2P | Owner's crit chance is increased by 8-16%. The owner's crit chance against opponents with HP less than or equal to 50% is further increased by 8-16%. When the wearer defeats an opponent, their attack power is increased by 20-40% for 2 turns. | A legendary light cone from Herta's shop that can be equipped if the previously discussed weapon "cards" are missing. Offers significant increases to crit chance, thus allowing you to look at other combat characteristics in the process of leveling artifacts. Additionally increases the chance of crit and attack power during combat, subject to the conditions stated in the Description. |
 Only Silence Remains | The wearer's attack power is increased by 16-32%. If there are two or fewer opponents on the battlefield, crit. the owner's chance increases by 12-24%. | Increases the character's attack power - a characteristic that affects the damage from basic skills, including bonus attacks. In addition, during a fight with two opponents or a solo target, it will affect the hero's crit chance, which again will significantly increase the damage he inflicts. |
 Final Victor | The wearer's attack power is increased by 12-20%. When the owner makes a crit. hitting an enemy, he receives 1 level of Luck status, which can stack up to 4 times. Each status level the owner has increases his crit. damage by 8-12%. The Luck status is removed at the end of the owner's turn. | Although the attack power will be useful to the hero, he is not able to maintain the maximum level of the "Luck" status in each turn. The specifics of the effect lies in the way the stacks are accumulated and reset: critical hits activate the passive and last until the end of the turn. The scientist can receive all 4 status levels during the next action after using the ult, where 2 bonus attacks of "Wiseman's Folly" will not reset the levels of "Luck". In other cases, bonus hits after the skill will receive a maximum of 2 stacks and will immediately disappear due to the end of the turn. |
Alternatively, you can consider:
- I Venture Forth to Hunt, Sleep Like the Dead, In the Night (legendary) - a variant of legendary equipment, which will offer a good bonus to outgoing damage, as well as significant increases to basic characteristics;
- Return to Darkness (epic) - a good option from the Nameless Honor, but in reality it has only one useful permanent bonus in the form of a stable increase in critical chance.
- "Adversarial", "Darting Arrow", "Arrows" (rare) - nothing more than a good early game alternative that can be upgraded to max superimposition in a very short amount of time.
What relics and ornaments are needed
When choosing artifacts, the main characteristics will be identical to those previously considered for weapon "cards". The ideal option is relics that provide increases to key attack bonuses, which include:
- imaginary damage;
- crit. damage and crit. chance;
- Attack Power.
Cavern relics
| The set is | Effect | Recommendation |
|---|---|---|
 | 2 parts: Increases damage dealt to enemies with Debuffs by 12%. 4 parts: Increases crit. 4% chance. The owner's crit damage dealt to enemies with at least 2/3 debuffs increases by 8%/12% respectively. After the owner applies a Debuff to an enemy, the above effects are increased by 100% for 1 turn. | The most effective set for a scientist due to the increase in overall damage dealt, which works for any attacking skills. Two parts of the set contain the main boost, and the condition for work is the presence of debuff on enemies. At the same time, the full set gives bonuses to crits and requires 2-3 debuff on enemies (80-100% chance of a bonus attack). For full implementation, you will need to level the "Inference" trace and take a stable debuffer as a partner. |
 | 2 parts: Increases damage dealt to enemies with Debuffs by 12%. 2 parts: Increases bonus attack damage by 20%. | The best option in a 2x2 combination, as the build combines a boost to the core mechanic and a percentage increase in damage. Due to the fact that it is important for the team to have several debuffs to play comfortably, the passive conditions of the two parts of the Pioneer are fulfilled naturally. |
 | 2 parts: Increases apparent damage by 10%. 4 parts: When the wearer deals damage to a debuffed enemy, their crit. the chance increases by 10%. When the owner deals damage to an enemy with the Imprisonment status, his crit. damage increases by 20%. | An equally suitable option in comparison with the above-considered 2x2 build, since in addition to the imaginary bonus, it offers increases to the main attack characteristics of the character. However, for the stable operation of the set, it is extremely important to either constantly break through the imaginary vulnerability for the "Ensnared" status, or have in the team Welt (Nihility). |
In addition, it is possible to consider 2x2 combinations of the following sets with "Pioneer Diver of Dead Waters" or "The Ashblazing Grand Duke":
- "Wastelander of Banditry Desert" — achieving a constant percentage increase in imaginary damage;
- Musketeer of Wild Wheat, "Prisoner in Deep Confinement", "The Wind-Soaring Valorous", "Hero of Triumphant Song" - a universal solution in the form of a stable increase in attack power;
- "Scholar Lost in Erudition" - an option for crit chance, which may be an acceptable option if there are problems with the named characteristic.
Planar ornaments
| The set is | Effect | Recommendation |
|---|---|---|
 | 2 parts: When allies make a bonus attack, the owner gains 1 lvl. “Merit” status, which stacks up to 5 times. Every level The “Merit” status increases the damage dealt by the bonus attack of the wearer of the planar set by 5%. Upon reaching level 5, the owner's crit damage is increased by an additional 25%. | The strongest planar ornaments on Veritas, as he mainly relies on bonus attacks. For a faster gain of stacks of enhancement, it is better to use the set together with another character from similar mechanics in the team. |
 Inert Salsotto | 2 parts: Increases crit. owner's chance is 8%. If critical If the owner's chance is greater than or equal to 50%, the damage of his superpower and bonus attack increases by 15%. | One of the best planar ornaments sets: it offers a boost to the damage output from the ultimate and, most importantly, the attack bonus. The main thing is to bring the character's crit rate to 50% to activate the effects of the set. |
 | 2 parts: Increases the owner's attack power by 12%. If there is at least one ally on the same Path as the owner at the start of the battle, the crit chance is further increased by 12%. | A set with a situational passive, but beneficial bonuses to the important for Veritas indicators of crit. chance and attack power. For the set to work, you will need to put a representative of the Hunt in the team with the hero. Given the specifics of the path, among the suitable characters, several units can be distinguished: Fire Topaz (legendary), Lightning Moze (epic). |
 | 2 parts: Increases the wearer's attack power by 12%. If the owner's speed is higher than or equal to 135/160, then the damage they deal increases by 12%/18%. | A good alternative in case you lack good parts of the above sets. Will provide a bonus to attack power, and will also passively increase the damage done by the scientist. The only caveat is that for the set to work properly, it is important to bring the hero's speed to the specified minimum (135). |
Alternatively, you can equip the following sets for the first time:
- Space Sealing Station - a versatile solution for the early and later stages of the game due to the fact that the set offers 24% attack power in total if the speed condition of 120 or higher is met;
- "Celestial Differentiator" — an option with a constant increase in critical damage if it is not possible to balance the character's characteristics (subsequently forcing you to resort to replacement due to unstable and narrowly targeted bonuses).
Team Guide for Dr. Ratio in HSR
Dr. Ratio's role in the team is built around the position of a main DPS character. Accordingly, to fully reveal the combat features of the damage hero, suitable units of Nihility and Harmony are selected, and universal protection is provided in the form of a follower of the Path of Preservation or Abundance.
Which characters are suitable?
Characters of Nihility and Harmony, who will most effectively reveal the advantages of the doctor, as well as DPS-type heroes, who can take the role of a secondary damage dealer:
| Character | Damage Path and Type | Features |
|---|---|---|
 |  The Hunt  Fire | Veritas and Topaz are characters that will be able to complement each other during battle: while Topaz offers boosts to the Scientist's bonus attacks, he will be able to promote the actions of Numby the Piggy. |
 | The Hunt  Lightning | Veritas relies on enemies being affected by 3-5 (ideally) debuffs during a battle to maximize their personal potential.

Best team samples
With the heroes discussed above, the following examples of teams can be created:
| Character 1 | Character 2 | Character 3 | Character 4 | Features |
|---|---|---|---|---|
 | | | | A classic team from constant bonus attacks, where the scientist and the representative of the IPC with Numby effectively complement each other. Robin acts as a universal Harmony, increasing the critical damage inflicted by bonus hits. At the same time, Cipher, being a hero of Nihility, offers debuffs and additionally carries out subsequent attacks. However, Pela will do in a budget version. |
| | | | An additional variant of the team with a high AoE focus, where Sustain is replaced by Lingsha, whose ultimate applies an additional debuff in the form of the "Befog" status. |
| | | | Moze acts as a secondary damage dealer, dealing frequent strikes from the shadows while an ally attacks enemy targets affected by the Prey status. Ruan Mei increases the overall combat effectiveness of the team, while applying an additional debuff with her Ultimate, which is necessary for Veritas. |
| |  | | A team with a hyper-carry Doctor who gets multiple increases to personal damage due to cooperation with two representatives of the highest tier of Harmony. Replacing Sunday with Trailblazer (Remembrance) suggests an additional expansion of third-party damage due to the true damage procs from Memo. |
| | | | A variant where the scientist's damage spectrum is expanded by Jiaoqiu, which additionally increases the damage from the allies' ultimate skills. Thus, Veritas' DPS potential is revealed not only thanks to bonus attacks, but also to a powerful super ability. The energy problem, in turn, is solved by units that are able to fill it. |
|  | | | A fake unit that demonstrates itself well in battles against enemies vulnerable to this element. In the event of a clash with an enemy of a different direction in terms of durability, it is permissible to replace Welt with the Silver Wolf, which is capable of imposing new types of vulnerabilities. |
| |  |  | A free team with stable damage that increases its combat potential thanks to Asta's ultimate "Astral Blessing", which greatly increases speed. |
|  | | | A F2P team with slightly more area damage, with Serval and Asta responsible for applying the Shock and Burn damage over time statuses. Gallagher, in turn, updates the Besotted debuff for better break power on some attacks. |
Is it worth pulling for Dr. Ratio?
Veritas is a strong representative of the Hunt, who has a unique gameplay. Compared to other followers of damage-dealing Paths, the scientist highly values heroes of the Path of Nihility, who are able to constantly maintain debuffs on enemies. Thanks to them, he not only deals high damage with active skills, but also receives additional bonuses to the main attack characteristics during combat.
Despite the difficulties that may arise when composing a team with a doctor, the character is extremely easy to bulid. For the light cones, most epic and even rare weapon "cards" are suitable for him, an equally attractive option can be "Cruising in the Stellar Sea" from Herta's shop. As for artifacts, there are quite a few acceptable 2x2 mixes among the cavern relics.
Considering that the hero's abilities are mostly good at dealing with single targets, the value of the Imaginary unit for clearing such a mode as "Pure fiction", drops significantly. Especially compared to others, capable of covering both the named mode and other high-level ones. However, even after many patches, the scientist remains an attractive combat unit, which can impress with the damage coming from bonus attacks. Accordingly, if the account requires a stable damage dealer with unique gameplay, Veritas will be an excellent acquisition.
