Cissy in ZZZ: Best Unit Guide and Build

Guide to Cissy in Zenless Zone Zero With an analysis of the "Poison" meter and the "Bone Eater" periodic effect. Through her passive skills, the heroine provides the team with a significant buff that ignites enemy defenses with electric DPS and a critical damage bonus. Her damage delivery method allows her to engage in close combat, and all her beneficial statuses combine to make her an excellent fighter with support capabilities.

Her build focuses on energy regeneration and balancing her core damage dealer stats. She has a decent budget-friendly booster and several limited-edition options, as well as a well-suited set of Drive Discs. Her only drawback is that without five-star Electro Agents, team building can be challenging, as she plays as a snake in mono-teams.

How to Get the Character

Cissia can be obtained in the banner of the second half of patch 2.7 in due time. from April 15 to May 5, 2026, and in the adjacent "Signal Search" there will be an opportunity to pick up her signature amplifier "Reptilolator".

To avoid missing the agent's rerun, follow the banner schedule in this article.

Strengths and Weaknesses

The former criminal is a great secondary damage dealer for teams with other electrical agents. She quickly activates her buffs and retreats into the field, giving the damage dealer and stunner constant time. Her main drawback is her narrow bonuses, which means she's only effective in a limited number of teams.

The Best Builds for Cissy in ZZZ

The key characteristic of the snake tyrena is energy recharge, because this stat determines how much of the enemy's defense will be ignored by the team's Electric DPS. Cissia also needs to improve her ATK (and, consequently, her Critical Chance and Damage) to maximize Bone Chewer's damage while she's "in the pocket." Other stats that will be useful include Percent Penetration, a bonus to Electric, and general DPS buffs.

Rating of amplifiers

Energy regeneration is a must-have weapon stat for Cissia. If it's replaced by another stat, she'll have to be on the field more often, taking time away from her primary damage dealer.

Amplifier	The effect	Recommendation
Reptilolocator (5⭐️) Basic ATK 48-714 In/e: 24-60%	Grants 25-40% Crit. chance. For every 20 energy spent at once, the agent's Electric DPS is increased for 3 seconds and he ignores 28-42% enemy defense. If the effect is reactivated, its duration stacks up to 30 seconds and does not decrease while the agent not on the battlefieldAt the start of the battle, this buff is granted for 10 seconds.	A signature variant for the snake. This skill consumes up to 60 energy to gain "Poison" and apply the "Bone Eater" effect, dealing damage over time and activating a buff.
Drill - red axis (4⭐️) Basic ATK 42-625 In/e: 20-50%	If the agent uses a strengthened E-class or C/A, B/A and dash attacks deal damage to 50-80% More electrical damage over 10 seconds. This effect can only occur once every 15 seconds.	A good A-rank weapon with a high energy regeneration rate. The passive effect has a 5-second cooldown, which, if misused, can deprive the girl of the buff until the next use of the skill.
Flames of battle (5⭐️) Basic ATK 48-713 In/e: 24-60%	Increases k/w by 20-32%When dealing fire damage with URNAthershock, damage from subsequent attacks is ignored. 15-24% enemy defense for 8 sec. (max. 2 lvl.).	Another option with a priority stat and a bonus to critical hit chance. The girl can take advantage of the passive effect of the amplifier. will be not able to.
Man-made heart (5⭐️) Basic ATK 48-713 CRIT Rate: 9,6-24%	Increases k/w by 15-23%When the owner deals damage with a non-lethal or enhanced special attack, they gain 1 boost charge. Each charge increases the owner's electrical damage by 12,5-20% , stacks up to 2 times. Each charge lasts 40 seconds, and the duration is calculated separately. While both charges are active, damage from non-lethal attacks and super abilities is ignored. 20-32% of the target's defence.	The sphere provides a large amount of critical chance and increases DPS due to the bonus to Electro and the ignoring of enemy defenses by both the enemy's B/A and ultimate.

What drives to install

The heroine is suited for general sets for electric damage dealers, secondary damage dealers, and supports. Of the "halves," we recommend Moonlight Lullaby и "Swing Jazz" +20% energy recovery. You can also combine sets from the table with each other and consider sets with a critical chance bonus ("Dyatlokor-electro") or critical damage ("The Song of the Branch and the Blade").

Set and its effects	Features
Thunderous heavy metal 2 Piece: Electric URN increases by 10%. 4 Piece: If there is an enemy on the field in a Shocked state, the wearer's ATK increases by 28%.	A good set for Snake, as it provides a bonus to Electro and increases ATK. Enemies will often be in a Shock state thanks to the periodic activation of Bone Eater and the team composition focusing on one attribute.
Blooming Sunrise 2 parts: increases damage to non-lethal targets by 15%. 4 parts: Increases non-lethal damage by 20%. Using a boosted offensive ability or ultimate increases non-lethal damage by 20% for 25 seconds. The duration is refreshed when triggered again.	Bone Chewer's periodic damage is considered non-performing, so the set is suitable for enhancing the main source of damage.
Astral voice 2 Piece: ATK +10% 4 Piece: When any squad member enters the battlefield with Quick Assist, the entire squad gains 1 level of the Astra buff (maximum 3 levels) for 15 seconds. Repeated uses refresh the duration. Each level of the buff increases the DPS dealt by the character performing Quick Assist by 8%. Only one buff can be active for a squad at a time.	If a support on a team lacks this kit, it's a good option for a girl. She often calls in quick support: a pressed B/A, enhanced with E-shot, and a super ability. She's a preferred option for teams with Sid.
Hormone punk 2 Piece: ATK +10%. 4 Piece: When the wearer enters combat readiness or is replaced, their ATK increases by 25% for 10 seconds. Activates every 20 seconds.	It's also a good option for ATK. Snake appears on the field frequently, but only briefly, and the set works well with that.

Recommended Stats

In the table, you can study which parameters you need to look for as “main” in drive disks:

How important are additional characteristics:

Energy Recovery > Critical Chance > Critical Damage > ATK (%)

Optimal combat stats when max level and fully equipped:

• energy recharge: up to 3,7 units (140% in total through equipment);
• crit chance: 65-80%;
• CRIT DMG: from 120% and above (an additional passive skill will give +50% to the characteristic);
• ATK: 2 units and higher.

Which banbu is suitable?

Among the Banbu, Electric and Buffer Bunnies are suitable for Cissia: the former will be able to deal more damage under her buffs, while the latter will help with energy accumulation or distribute additional buffs.

Stekerbu	Elektrobu	Mercury	Mrs. Esme
Nutcracker	Barobu	Knighthood

Cissia's Squad Guide in Zenless Zone Zero

The main bonus the Tyren Snake grants to allies through Bone Eater is ignoring the defense of Electric-type damage. The bonus also includes effects that are increased if the pack contains characters of its attribute:

• The stun from Bone Eater is increased by 40%/60% if there are 1/2 Electro-equipped agents in the team besides the girl.
• The entire squad's K/U increases by 40% if the party includes an Agent of Intimidation or its attribute. The heroine grants herself a +50% bonus.

Therefore, teams for Cissy are necessarily composed with an electric main DD and closed by a character with support-buffer functions.

Best allies

The Tyren Snake performs best in a squad with the following agents:

Character	Features
Sid (Assault, Electro)	A unique character that enhances both herself and her Assault class partner. She and Snake form a mutually beneficial and self-sufficient partnership.
Soldier 0 (Assault, Electro)	While the snake doesn't buff Aftershocks, Soldier 0's primary damage type, it does increase all DPS dealt through its Electric DPS defense ignorance.
Harumasa (Attack, Electro)	Harumasa deals large amounts of damage to stunned enemies, which synergizes well with the snake's ability to passively fill the stun bar with Bone Chewer.
Trigger (Intimidation, Electro)	An excellent "pocket" stunner with decent damage and a useful passive that increases the vulnerability multiplier of enemies.
Dialing (Intimidation, Phys.)	A stunner with a fast rotation, a powerful stun, and a ton of bonuses for herself and her allies. It can forcefully activate the ultimates of heroes in the group, replacing their attack chains.
Ju Fufu (Intimidation, Fire)	Increases the team's critical damage when combined with Snake. A good stunner if you don't have any other options.
Qingyi (Intimidation, Electro)	A hero who prefers to play the field and gradually inflict stuns. Her distinguishing feature is a high vulnerability multiplier on stunned targets.
Sanna (Support, Phys.)	The deposit significantly increases the damage of Attack agents and generally increases ATK, strengthening their DPS.
Astra Yao (Support, Ether)	A very flexible support that can help Snake buff her main damage dealer, get onto the field more often with quick assists, and deal more damage with a variety of large buffs.
Rina (Support, Electro)	An ideal and accessible support for mono-electric builds. Her passive prolongs Shock on enemies and increases their shock damage, while also restoring energy to allies with her ultimate.
Anton (Attack, Electro)	A free-to-play alternative to the main damage dealer role in a group. Relies on Shock on enemies, which can trigger E-class attacks with critical hits.
Nicole (Support, Ether)	A good F2P support: it reduces enemy defense and provides a critical chance bonus at M6, which helps your teammates reach the critical hit point.

Best team samples

Based on all the passive requirements, the girl should be placed in a secondary position in mono-electric teams:

Character 1	Character 2	Character 3	Features
Sid	Cissia	Sanna	The best team with Cissy. Together with Sanna, they buff Sid: they increase his shock damage, boost his ATK, and provide him with damage/hit and damage/kill.
Sid	Cissia	Trigger Dialing	A premium unit focused on maximizing Sid's strength. Trigger can increase her vulnerability multiplier outside of a stun, and Dialing grants multiple procs of her ultimate to her damage dealer.
Soldier 0	Cissia	Trigger Orpheus	The Armed Forces teammates work well together, boosting each other's Aftershocks. Cissia, in this team's variations, boosts DPS with her Poison passive and critical hit bonus.
Harumasa	Cissia	Qingyi Trigger	Harumasa is an agent who's more comfortable rotating when the enemy is stunned. Agents of Intimidation and Cissia's Bone Eater are good for this.
Anton	Cissia	Rina	A F2P squad can be led by Anton, who activates Shock on enemies. Rina extends the duration of the attribute effect and provides penetration, while Cissia inflicts critical damage on an ally and helps with enemy attrition.
Cissia	Trigger	Astra Yao	Although Snake feels best in the role of support DD, this squad allows you to try her out in the role of main DD.

Features

Basic parameters that increase with level:

Pumping up the inclinations increases energy recovery with 1.32 to 1.56 and ATK from 863 to 938 units.

Leveling

To develop the Tyren-snake, the standard materials for Electro Agents are required:

Leveling	Materials	Cost
Level	×4 Entry Level Attack Token ×32 Top Level Attack Token ×30 Pioneer Token	×800 000
Skills	×25 Basic Shock Chip ×75 Advanced Shock Chip ×250 Specialized Shock Chip ×5 Pass to the Hamster Cage	×2 495 000
Makings	×60 High-Dimensional Data: Bloody Corrupted Feather ×9Transformed shell	×405 000

How the skills work

In combat, the snake relies on "Poison" charges, which allow allies' electrical damage to bypass their target's defenses. These stacks transform into "Bone Chew" and deal damage over time every 5 seconds. They are acquired through an EX skill, chain attacks, and Super abilities.

• Basic attack: Hits help build up Poison stacks and use them to activate the Bone Eater effect (counts as a non-attack). This increases your own critical chance and is reflected on enemies as a flash of ball lightning. It is the main source of damage.

• Skill: Allows you to build up Poison even faster, spending 20 to 60 energy, and deals significant electrical damage to enemies. Quick Aid activates immediately after use.
  
• Evasion и help: a standard set of moves for avoiding damage and entering the field.

  

  

• Chain of attacks (c/a) also helps to accumulate "Poison", and the ult Activates an etheric curtain, increasing the squad's K/U.
  
• Main Passive Ability: Grants a bonus to ignoring Electro damage defense if the former criminal's energy recovery is above 1,4 units. The skill also details the operation of "Poison" and "Bone Eater."
  
• Additional ability: If there are Intimidation or Electro-attribute agents in the squad, the critical damage of Cissy and her allies is increased.
  

The order of leveling skills

Prowess = Special Attack = Basic Attack >> Chain Attack > Assist = Evasion

The heroine has three main skills, into which resources should be invested in parallel:

1. Traits - the snake's usefulness to the squad depends on them.
2. Skill - an ability that is used during rare arena appearances.
3. Basic attack - contains Bone Eater multipliers.

Leveling up your super ability will also have a positive effect on damage, and assists and evasions are no longer a priority.

The best eidoses

By knocking out duplicates, you can open the mental picture of the snake and activate passive effects.

The best consts of Cissia are the first one и second:

• The M1 contains a variety of powerful team buffs, making it a worthwhile investment for a snake.
• M2 adds "Poison" and significantly increases the damage of both non-lethal and target-oriented enemies, increasing the heroine's "pocket" DPS.

Other attachments are more useful for personal damage: M3 and M5 provide additional skill levels, while M4 and M6 trigger special variations of Bone Eater.

Knockout priority: M1 > signal > M2Since the budget "Bur-Red Axis" suits the girl well, the first constant with various enhancements will be more useful.

How to play as Cissia

In ZZZ, it's crucial for Cissia to maintain sufficient Poison and replenish it promptly. All other effects are activated automatically through a simple rotation:

1. At the start of the battle, the girl gains 3 stacks of "Poison." Perform a short special attack, spending 20 energy, and then attack with a basic attack. Then activate Quick Assist on the next agent.
2. Keep an eye on your energy buildup and remaining charges—as soon as you reach 1 charge, summon your heroine and spend all your energy. This will give her up to 5 more stacks.
3. If energy is generated faster than stacks are spent, then periodically press "E" to instantly activate "Bone Eater".
4. Don't forget to monitor your decibels and try to activate your ult after your enemy is stunned.

Is it worth knocking out Cissia?

Cissia is a strong sub-DPS who can deal damage over time from the pocket. She also serves as a support/buffer, increasing allies' critical damage, granting a bonus that pierces the defenses of lightning DPS, and even deploying an Ethereal Veil. She has a simple rotation, an easy build, and affordable gear, including an excellent budget-friendly booster.

A major drawback is the lack of flexibility when composing a team—she's not just dependent on having Electro allies; she requires a partner with her primary damage dealer. Therefore, she should be picked by those who need to strengthen their mono-Electric team or plan to target Electro damage dealers in the future. Other heroes won't benefit from her bonuses.
