Rappa in Honkai Star Rail: A Guide to the Best Build

Rappa in HSR — a legendary representative of the Path of Erudite of the imaginary element type. She calls herself a ninja and wanders through outer space, being Galaxy Ranger, and in his free time he likes to rap and draw graffiti. He is a damage-dealing character who is effective in fighting against a group of opponents due to stable mass damage and the ability to destroy opponents' "shields" in a short period of time.

Since Ninja specializes in penetration, she needs to select her allies and gear so she can constantly drain enemy stamina while simultaneously accumulating special charges to boost her damage output. Consequently, she excels when paired with support characters who increase her penetration or buff this type of damage to maximize her abilities.

How to Get the Character

Rappa can be obtained in the limited-time Event Warp: Character banner, which is called 'Eyes of a Ninja'.

To catch Rappa's next rerun in Honkai: Star Rail, keep an eye on the banner schedule.

Strengths and Weaknesses

Ninja Ranger is a hero who relies on draining enemy stamina. She excels in her niche, especially in AoE content and with the right supports. However, her core mechanics have limitations, such as a significant damage penalty if opponents can't be pierced.

Best Rappa Builds in Honkai: Star Rail

Ninja Girl is a fictitious DPS character, playing from the destruction of enemy "shields" and causing damage over an area. Given the specifics of skills, Rappa's build in XSR is based on the development of such indicators as break effect (EP) and attack power (ATK). There is also a need for speed, which is initially low due to the fact that the unit belongs to the Path of Erudition.

At the same time, it is important to note that "break" damage does not depend on critical values ​​(crit rate and dmg). Accordingly, these stats are not in demand when building the heroine. They will only affect the instant damage from skills and will only further complicate the build without bringing significant improvements. For this reason, it is better to give preference to other parameters.

Recommended Stats

Upper stats of artifacts:

Recommended lower stats:

Speed ​​> EP > ATK

Optimal values ​​of characteristics at the maximum level of hero development:

• EP: 160-250% and more.
• Speed: 145-150+.
• ATK: 2 or 900 to get the full bonus from the "Ninjutsu Inscription: Withered Leaf" trace.
• HP (health): 2+.
• DEF: 800 and more

Light Cone Rating

The most suitable cone would be the signature cone, but other options can also be considered:

Light cone	Effect	Recommendation
Ninjutsu Inscription - Dazzling Evilbreaker ⭐⭐⭐⭐⭐ HP 48-1058 ATK 26-582 DEF 21-463	Increases break effect by 60-100%. Immediately upon entering combat restores 30-40. energy. After the owner uses the super ability, the "Thunder Relief" status is activated. When the character performs 2 basic jabs, their action moves forward by 50-70%, and the status disappears and is updated the next time the ult is used.	Signa offers a boost to one of the key stats. Equally important, it always provides energy at the start, allowing you to quickly charge your super ability and enter the "Seal Form" state. Subsequently, your basic attack will advance the action, making your rotation more comfortable.
After the Charmony Fall ⭐⭐⭐⭐ HP 38-846 ATK 21-476 DEF 18-369	Increases break effect by 28-56%. After using the superpower, the character's speed increases by 8-16% for 2 turns.	Besides the signal, this cone is the only one that provides a bonus to EP, making it a viable option. At the same time, activating the ultimate increases movement speed, which positively impacts combat potential due to the increased frequency of actions.
Eternal Calculus ⭐⭐⭐⭐⭐ HP 48-1058 ATK 24-529 DEF 18-396	Increases ATK by 8-12%Each hit target increases ATK by another 4-8%The bonus stacks up to 5 times and lasts until the next attack. If the number of enemies hit is greater than or equal to 3, the speed is increased by 8-16% for 1 turn.	Since she consistently deals damage to all enemies with her skill and an improved version of her regular poke, she fully activates her passive ability and gains all available buffs. She excels in the "Pure Fiction" mode.
Night on the Milky Way ⭐⭐⭐⭐⭐ HP: 52-1164 ATK: 26-582 Defense: 18-369	Depending on the number of enemies, attack power increases by 9-15%. The bonus can be stacked up to 5 times. If there is an enemy on the battlefield with a broken weakness, the character's damage increases by 30-50% within 1 turn.	The weapon "card," like the previous one, is designed for fighting against groups of enemies. In addition to increasing ATK for each enemy on the battlefield, it can also increase damage dealt. The latter requires the presence of at least one enemy with depleted stamina.
The Seriousness of Breakfast ⭐⭐⭐⭐ HP 38-846 ATK 21-476 DEF 18-396	Damage dealt is increased by 12-24%. Each enemy destroyed additionally increases the character's attack power by 4-8%. The bonus can be summed up to 3 times.	All damage inflicted is increased without any conditions, and ATK also increases based on the number of enemies defeated. The heroine is primarily used in situations where she must fight multiple enemy targets, so she activates buffs effortlessly.

If you don’t have the weapons discussed in the table, you can use:

• Make the World Clamor (Epic) - an option for generating more energy if there's no signal, and the superpower doesn't charge in time. However, it's important to note that the second part of the passive effect doesn't work.
• Today Is Another Peaceful Day (Epic) - Increases overall damage based on the player's maximum energy. This superpower costs 140 energy, allowing the passive bonus to be utilized almost entirely.

What relics and ornaments are needed

Artifacts are selected similarly to weapons and take into account the basic needs of the character. Since the damage from depleting enemy stamina is also affected by the decrease in defense, you can equip the corresponding sets.

Cavern relics

Set and its effects	Recommendation
Iron Cavalry Against the Scourge 2 parts: break effect +16%. 4 parts: If the enemy's EP is at least 150%, 10% of their defense is ignored when dealing penetration damage. If the value is above 250%, super penetration damage ignores an additional 15% of their defense.	One of the best positions for unlocking a character's potential. The key requirement is a threshold of 150% EP. The heroine can also fully utilize the set if she gains stats from other sources.
Thief of Shooting Meteor 2 parts: break effect +16%. 4 parts: Penetration effect +16%. If an enemy's weakness is penetrated, 3 energy units are restored.	Decent equipment that helps you get closer to achieving the recommended value. It also speeds up the Super Ability gauge and the transition to the "Sealing Form" state, which unlocks enhanced weaponry.
Iron Cavalry Against the Scourge 2 parts: break effect +16%. In combination with sets: Watchmaker, Master of Dream Machinations / Thief of Shooting Meteor (2 parts) - break effect +16%. Messenger Traversing Hackerspace (2 parts) - speed +6%.	2x2 Relics to achieve the required stats and fill the corresponding "gaps" in the build. This type of build is convenient if the aforementioned sets with the required parts in the upper and lower stats are unavailable.

A more specific, but acceptable option is: Eagle of Twilight Line, which advances the action after using the ultimate. This set is especially effective in the late game, especially if the Ninja can perform three actions per rotation.

Planar ornaments

Set and its effects	Recommendation
Talia: Kingdom of Banditry 2 parts: Penetration effect +16%. If the speed is 145 units or higher, EP increases by an additional 20%.	A set with a key stat. To activate the maximum increase to this stat, you need to "accelerate" your movement speed to 145. This can be achieved not only by using third-party gear like Relics and Cones, but also by using support gear.
Forge of the Kalpagni Lantern 2 parts: Speed ​​+6%. If the character deals damage to a target with a weakness to the fire element, EP increases by 40% for 1 turn.	An alternative set that increases HP and also grants speed. However, its effectiveness varies depending on the battlefield situation: if enemies are weak to fire, it becomes stronger than Taliyah, while otherwise, it loses by about 4%.
Space Sealing Station 2 parts: Attack Power +12%. If Speed ​​is 120 or more, ATK increases by another 12%.	An easy-to-implement yet versatile set with a 24% ATK bonus. Activating the passive shouldn't be a problem in this case, as equipping the Speed ​​Boots is sufficient. A great option at any stage.

Team Guide for Rappa in HSR

In a team, Rappa plays the role of a damage dealer, focused on clearing out groups of enemies. Due to her unique nature, she pairs well with supports that boost her HP or, alternatively, offer bonuses to attack power, speed, and DPS.

In this case, the squad can be successfully supplemented with debuffers or units of other Paths. In both cases, it is desirable for the characters to break the toughness of opponents as often as possible and thereby help to gain talent charges.

Which characters are suitable?

Suggested allies that can be included in the group:

Character	Features
Georgina (Non-existence: Fire)	Constance's ultimate makes enemies vulnerable to the Dance Partner element (applied to the one who started the fight or has the highest HP). Considering the ninja doesn't inflict weakness to her element, this is very useful. Equally important, the demoness can inflict super penetration even if the enemies' durability isn't completely reduced.
Fugue (Nihility: Fire)	One of the best supports. Allows you to gain charges faster and charge your ultimate by frequently breaking your stamina. This doubles the bonuses provided by the talent. Another benefit is the defense reduction.
Silver Wolf (Nihility: Quantum)	The Stellaron Hunter is useful in areas where elite enemies are present, as it can inflict a false elemental vulnerability on them. This will make it much easier to destroy the enemy's weakness.
Pela (Nihility: Ice)	Pelageya focuses on reducing enemy defenses with her ultimate. Considering this affects the damage dealt by penetration, she's a great addition as a debuffer.
Ruan Mei (Harmony: Ice)	She's considered a versatile support. The only downside is that her ultimate makes it a bit more difficult for the ranger to build up charges due to the longer it takes for enemies to recover from armor depletion.
MC (Harmony: Imaginary)	The False Hero significantly boosts EP and also allows for additional super-piercing damage in addition to the Ninja's own mechanics. Doesn't consume many skill points.
Tribbie (Harmony: Quantum)	Increases penetration of all resistance types and also deals damage with her bonus attack and ultimate, allowing Rappa to accumulate talent charges when her stamina is depleted.
Tingyun (Harmony: Lightning)	The ultimate restores energy, which is no less beneficial for a Ninja Ranger than the speed boost. It also increases overall damage, and the skill increases ATK.
March 7 (Hunt: Imaginary)	Transforms one ally into a Teacher and grants bonuses, allowing for additional damage. March also possesses useful traits: it reduces durability based on the Teacher's element and increases EP.
Lingsha (Abundance: Fire)	A powerful healer who inflicts a negative status on enemies, increasing damage. Specializes in summoning a creature that passively heals and helps deal with enemy targets.
Gallagher (Abundance: Fire)	A budget replacement for Linsha. Works best in teams that drain stamina, forcing enemies to take more damage when their bar is completely depleted.

Best team samples

The table shows the best units for Rappa:

Character 1	Character 2	Character 3	Character 4	Features
Rappa	Dahlia	Ruan Mei Fugue MC Harmony	Lingsha Gallagher	A premium build in which Georgina, along with other breakable supports, provides the ninja with essential buffs. Healers, meanwhile, optimally complement the squad with debuffs that increase enemy penetration damage.
Rappa	MC Harmony Tingyun March 7	Dahlia Silver Wolf Pela	Aventurine Lynx	A squad that provides both direct buffs and deals increased damage through debuffs applied to enemies by Path of Nothingness heroes. Dahlia (can be replaced with Fugue), Silver Wolf, or Pela are excellent candidates for debuffing roles, as they reduce enemy defenses.
Rappa	Boothill Firefly Xueyi	Dahlia Fugue MC Harmony	Lingsha Gallagher	A squad with a second penetration character. While Boothill and Xuei can be quite frugal with action points and perform more secondary functions, with Firefly, the ninja takes a back seat.
Rappa	The Herta	Tribbie Ruan Mei	Lingsha Permansor Terrae	A team with Great Gerta needs a second Path of Erudition hero. While she doesn't rely on penetration, she can reduce the durability of ice enemies and help build stacks. The remaining positions are filled with versatile supports that complement both heroes.

How skills work

The Ninja is an Imaginary damage dealer who deals massive damage primarily through toughness break. During combat, she relies on a strengthened basic attack, which is activated by using super ability and receives additional bonuses due to talent.

Active skills

Passive Skills

Leveling Order

Talent > Super Ability > Basic Attack > Skill

It is recommended to develop all skills, since the heroine is a damage dealer. However, initially you can adhere to the following sequence:

1. Talent - allows you to deal much more damage with enhanced b/a due to the accumulation of charges.
2. Superpower - is a buff and will affect the amount of EP increase received.
3. Basic Attack - Affects not only the normal version, but also the hit received during the "Sealform" state.
4. The skill itself does little damage compared to the previous skills, but will be useful while the enhanced strike is inactive.

Traces

Ninja Girl's Talent Tree:

• "Ninjutsu Inscription: Sky High" (A2): breaking the vulnerability of elite enemies or stronger targets restores 1 talent charge and 10 energy.
• "Ninjutsu Inscription: Sea Echo" (A4): While in Seal Form, after using a Powered Basic Attack against a pierced target, the Tenacity damage is converted into a strike that deals 60% Super Pierce damage.
• "Ninjutsu Inscription: Withered Leaf" (A6): When an enemy's weakness is destroyed, their piercing damage is increased by 2%. If their ATK is above 2400, the bonus increases by 1% for every 100 additional ATK (maximum 8%). This lasts for 2 turns.

Total bonus to characteristics:

Eidolons

The best Eidolons of Rappa are the first, second and sixth ones:

• E1 Allows you to ignore enemy defense when performing a powerful basic attack, increasing overall DPS. At the same time, when the "Sealform" state ends, additional energy is given.
• E2 similarly buffs the enhanced b/a. However, in this case, the durability damage is increased only for the first 2 strikes, which are distributed to one enemy and adjacent enemy targets.
• E6 Increases the talent's charge accumulation limit to 15, and also provides the heroine with additional charges immediately after entering battle or performing her 3rd enhanced strike.

F2P players are advised to stop at getting their first Eidolon.

How to play Rappa in HSR

During battle, the heroine strives to quickly build up energy and enter the "Seal Form" state using her superpower. In this state, the Galactic Rangers ninja can only use her enhanced jab, which is her primary source of DPS. In other words, the gameplay involves consistently using a skill (sometimes a standard attack) to activate her ultimate and enter the special mode. Ideally, this requires the heroine and her allies to constantly breach enemy weaknesses to accumulate talent charges for additional damage.

Let's take a closer look at Rappa's rotation:

1. Before the battle begins, it is recommended to use a technique that allows you to inflict significant damage to several enemies at the start and restore 10 units of energy.
2. Use the skill to hit all enemies at once and still get enough energy. The regular basic attack is only used in extreme cases. For example, if you need to save or restore action points.
3. When the super ability is charged, activate it to enter the Sealform state and gain 3 Chroma Ink charges (the number of upgraded strikes available). The skill and ultimate will be unavailable during this state.
4. After the super ability, perform a basic attack with a boost 3 times. The remaining amount of "Chroma Ink" is indicated on the left above the health bar, and below the HP are talent charges for increasing damage.
5. Continue attacking until the condition ends, then repeat the rotation from step #2.

To deal as much damage as possible with the last hit in the "Sealform" state, target the first 2 attacks of enemies that can be broken. However, if the charges are needed more in the next wave, it is optimal to do the opposite: do not specifically reduce the stamina bar with the first 2 hits, leaving this for the final hit.

Is The Character Worth Pulling?

In Honkai: Star Rail, Galactic Rangers Ninja Rappa focuses on dealing fake area damage and constantly draining her opponents' stamina by penetrating their vulnerability. In combat, she relies on a boosted basic attack, granted through the "Seal Form" superpower, while also providing herself with useful buffs, such as increased effectiveness and a piercing effect.

Gameplay-wise, she's straightforward—the main goal is to use her skills and then activate her ultimate to enter an enhanced combat mode. While she doesn't boast much versatility or exceptional options compared to other damage dealers, she excels in content that requires AoE damage. Overall, she's worth picking if you prefer to play for penetration and also need someone who excels in modes like Pure Fiction.

Which is better: signature or E1

Signature Weapon is an optimal investment, as it's one of the few cones that increases EP. It also provides energy at the start of battle, speeding up the transition to Seal Form. Subsequently, the "card" advances the action for every two hits, making it easier to gain energy through more frequent actions.

The first Eidolon is an equally powerful option, as it lowers enemy defense while using the enhanced b/a and also restores energy. However, the light cone becomes preferable thanks to wider functionality, making gameplay more comfortable and simplifying assembly.
