5: Position 5 is Chu’s optimal slot where he is maximally protected by front-line tanks while continuously applying echoing status and reflecting hits from the safest position.
4: Position 4 lets Chu act slightly earlier in the turn order while still being shielded by three front-row heroes, useful when faster Echo 2-piece round 1 Death Symphony timing matters.
3: Position 3 is a flex option that places Chu closer to the front for earlier action but increases his exposure to enemy damage, only viable with strong front-line protection.
Chu is the Vindicators’ premier AOE carry whose Death Symphony applies an echoing status to all enemies, causing them to take 30% extra TAC DMG from Chu whenever they receive damage, creating a cascading damage loop across the entire enemy team. His Hidden Strike adds reflecting hits on normal attacks that deal TAC DMG to random targets, and Call of Death heals allies who attack echoing targets while granting Chu Focus, accelerating his Focus skill cycle. Resonance Mic UW stacks +10% crit rate per Focus skill (3x), +10% Crit Immunity per hit taken (3x), and +2% ATK per Call of Death trigger (15x), making Chu increasingly dangerous as battles extend.
Pros & Cons
- Death Symphony applies echoing to all enemies, creating cascading AOE damage every time any echoing target takes damage from any source
- Echo 2-piece casts Death Symphony at round 1 without waiting for Focus, guaranteeing immediate echoing application on the entire enemy team
- Call of Death heals allies who attack echoing targets for 50% of Chu’s TAC ATK, providing significant sustain from a DPS hero
- Resonance Mic UW permanently stacks +2% ATK per Call of Death trigger (up to 15 stacks), scaling Chu’s damage throughout extended fights
- Echo 4-piece adds 2 more reflecting hits prioritizing echoing targets, amplifying Hidden Strike’s normal attack damage output
- Requires Dimension X1 unlock and Echo exclusive gear to reach full potential, making him investment-heavy
- Echoing status expires after 2 triggers (3 with Death Finale), requiring periodic Death Symphony recasts to maintain pressure
- Low VIT (299) makes Chu extremely fragile if front-line protection collapses
- Graceful Spin’s 18% dodge chance is unreliable and cannot be counted on for consistent survival
Skills
Deals 60/68/76/84/100% TAC DMG to all enemy targets and applies the echoing status to them ((Echoing: when taking DMG, takes 18/20.4/22.8/25.2/30% extra TAC DMG from Chu; expires after being triggered 2 time(s)).
Applies the reflecting effect 2 times in a normal attack, dealing 25/30/35/40/50% TAC DMG and 12.5/15/17.5/20/25% TAC DMG to random targets respectively each time.
When your Heroes attack enemy targets subjected to the echoing status. they will restore some equal to 25/30/35/40/50% of Chu’s TAC ATK, and Chu will gain 25/30/35/40/50 Focus.
When casting the "Death Symphony", deals 10/12/14/16/20% extra TAC DMG: the max times that the echoing status can be triggered +1.
When being attacked, 9/10.8/12.6/14.4/18% chance to be immune to DMG this time.
Gear
Echo is mandatory for Chu to unlock round 1 Death Symphony and the enhanced reflecting hits. Pair with Resolute for survivability or Hurricane for maximum AOE output. The round 1 echoing application is the difference between Chu dominating from the start or losing critical damage windows.
Chu’s exclusive set and the cornerstone of his kit. 2-piece casts Death Symphony at round 1 and heals the lowest-HP teammate 75% of Chu’s TAC ATK on each Call of Death trigger. 4-piece adds 2 extra reflecting hits prioritizing echoing targets. Non-negotiable best-in-slot.
#1 Best
Versatile set providing WPN DMG and death immunity, ensuring Chu survives burst attempts that would otherwise end his echoing damage loop prematurely.
#2
High-damage endgame set that maximizes Chu’s raw TAC damage, pairing well with Echo’s reflecting hits for maximum per-hit output.
#3
Aggressive damage set pushing Chu’s burst higher at the cost of survivability, best in lineups with strong healing support to compensate.
#4
AOE-oriented set that amplifies Chu’s multi-target damage output, boosting both Death Symphony’s initial hit and the cascading echoing damage across all enemies.
#5
Chu’s substats prioritize INT and DMG Bonus on weapon and jewelry to maximize TAC damage output, while helmet and body focus on survivability to protect his fragile 299 VIT stat line. Crit Rate on the weapon is particularly valuable since Resonance Mic stacks additional crit rate per Focus skill, creating compounding returns.
DMG Bonus, INT, Crit Rate
DMG Bonus and INT directly scale Death Symphony’s and Hidden Strike’s TAC damage, while Crit Rate feeds into Resonance Mic’s stacking crit mechanic for compounding returns.
HP%, AGI, VIT
HP% and VIT compensate for Chu’s low base VIT (299), while AGI improves action order to ensure Death Symphony’s echoing status is applied before allies attack.
DEF, VIT, DMG Mitigation
Defensive substats keep Chu alive in the back row, ensuring he survives long enough for Call of Death’s cumulative ATK stacking and team healing to reach full value.
DMG Bonus, INT, Crit DMG
DMG Bonus and INT maximize Death Symphony’s raw AOE damage, while Crit DMG amplifies critical echoing hits for devastating cascading damage.

Beast 
Crimson Predator amplifies Chu’s and Blanche’s damage output, ensuring the team has enough firepower to capitalize on Casino’s disruption and kill echoing targets before they recover.
Primary tank providing Rivets +45% Crit Rate to amplify Chu’s and Blanche’s damage while Dark Shark protects back-row carries from taunt effects.
Core disruption tank whose immediate Double Down drains 200 Focus from all enemies, crippling their Focus skills while Chu’s echoing damage cascades across debuffed targets.
Chain tank linking echoing enemies together so Chu’s cascading damage conducts through chains, effectively multiplying the echoing damage loop across all connected targets.
Primary AOE carry whose round 1 Death Symphony applies echoing to all enemies. Every subsequent hit on echoing targets triggers 30% extra TAC DMG and Call of Death healing, creating a self-sustaining damage engine.
Secondary carry assassinating focus-drained back-row enemies whose echoing status amplifies the damage they take from Blanche’s crit-boosted Eradicates.
The premier Vindicators lineup from X3 onward pairing Casino’s focus drain disruption with Chu’s echoing AOE damage for a control-and-damage combination that overwhelms most compositions. Casino in position 2 forces enemy carries to attack only him and drains 200 Focus per dice loss, while Chu’s round 1 Echo-powered Death Symphony immediately applies echoing to all debuffed enemies. Ricardo’s chains spread echoing damage through conduction while Blanche assassinates focus-drained back-row targets.
Beast
Crimson Predator boosts the lineup’s overall damage output, ensuring Chu’s echoing damage and Blanche’s burst are sufficient to overwhelm enemy healing.
Primary tank providing Rivets +45% Crit Rate and front-line durability. Band Festival’s +5% DMG Bonus benefits Chu’s echoing damage and Blanche’s burst.
Chain tank linking enemies so attacks on chained echoing targets spread damage and trigger additional Call of Death healing from Chu, amplifying the sustain loop.
Core AOE carry and sustain engine whose round 1 Death Symphony applies echoing to all enemies. Call of Death heals allies for 50% of Chu’s TAC ATK per trigger, sustaining the team through attrition.
Primary single-target carry whose attacks on echoing targets trigger Call of Death healing while dealing devastating crit-boosted Eradicate damage.
AOE damage dealer whose Big F Bomb hits all echoing enemies, triggering multiple Call of Death healing instances per cast and softening targets for Blanche’s assassinations.
An early-season Vindicators lineup available from X1 that leverages Chu’s Call of Death healing to sustain the team through extended fights. Chu’s echoing damage creates a self-healing loop where allies restore HP every time they attack echoing targets, and Ricardo’s chains maximize the number of echoing interactions per round. Quinn provides AOE pressure and DEF reduction while Blanche delivers single-target burst.
Beast 
Metallic Dragon enhances front-line durability for Buri, Enrique, and Ricardo, ensuring the triple-tank wall holds long enough for Chu’s cumulative ATK stacking and echoing damage to overwhelm the enemy.
Primary tank whose Link of Life distributes damage across all linked allies, preventing any single hero from being burst down while Chu’s Call of Death healing sustains the entire team.
Secondary tank providing Rivets +45% Crit Rate and Dark Shark taunt protection. Band Festival’s +5% DMG Bonus amplifies Chu’s echoing damage output.
Chain tank linking enemies for conduction damage while High Voltage provides stacking DMG Mitigation, adding durability to the already resilient Buri-anchored front line.
Core AOE carry whose Call of Death healing sustains Buri’s damage-distributed allies. The extended fight duration maximizes Resonance Mic’s +2% ATK stacking for scaling damage output.
Single-target burst carry whose attacks on echoing targets trigger Call of Death healing while delivering devastating crits boosted by Enrique’s Rivets.
A durable attrition lineup that pairs Buri’s Link of Life damage distribution with Chu’s Call of Death healing for a near-unkillable sustained damage composition. Buri distributes incoming damage across all linked allies while Chu’s echoing mechanic heals every ally who attacks echoing targets, creating a sustain loop that extends fights long enough for Chu’s Resonance Mic ATK stacks to reach maximum value. The extended fight duration maximizes Call of Death triggers and Chu’s permanent ATK scaling.
Synergies
Casino’s Double Down drains 200 Focus from all enemies while Chu’s echoing status deals extra TAC DMG every time those focus-drained enemies take damage. The combination creates a state where enemies can neither use Focus skills nor avoid cascading echoing damage.
Ricardo’s chain-linking on echoing enemies causes conduction damage to spread across all connected targets, and each conduction hit on an echoing target triggers additional echoing damage from Chu, creating a multiplicative damage loop.
Enrique’s Rivets +45% Crit Rate dramatically increases the crit chance of Chu’s Death Symphony and reflecting hits, which compounds with Resonance Mic’s stacking +10% crit rate per Focus skill for near-guaranteed crits in later rounds.
Blanche’s Eradicate on echoing targets triggers Call of Death healing while dealing massive single-target burst, creating a dual-DPS pairing where Chu provides AOE pressure and sustain while Blanche delivers targeted kills.
Buri’s Link of Life damage distribution extends fights significantly, giving Chu more rounds to accumulate Resonance Mic ATK stacks and Call of Death triggers, maximizing his late-game scaling potential.
Interactions with other heroes’ ultimate weapons.
Dark Shark protects two heroes behind Enrique from Taunt effects. When Chu sits in position 4 or 5, this prevents enemies from taunting Chu out of his safe back-row position, ensuring uninterrupted echoing damage output.
Grand Debut chains 2 random enemies at battle start, immediately creating conduction links before Chu’s round 1 Echo-powered Death Symphony applies echoing. Attacks on chained echoing targets trigger both conduction and echoing damage simultaneously.
Hellfire Axe’s permanent +20% Backlash stacking on dice losses draws enemy attention and damage toward Casino, indirectly protecting Chu’s fragile 299 VIT stat line while Casino absorbs hits that would otherwise threaten the primary AOE carry.

Counters
- Burst Damage Lineups (Hard Counter) — Lineups that can kill Chu before his echoing damage loop establishes bypass his scaling mechanic entirely, since Death Symphony needs time to trigger multiple echoing interactions for maximum value.
- Silence Effects (Hard Counter) — Silence prevents Chu from casting Death Symphony, removing echoing status application and shutting down his entire damage engine including Call of Death healing.
- AOE Cleanse (Soft Counter) — Abilities that cleanse debuffs remove echoing status from enemies, forcing Chu to reapply Death Symphony and losing accumulated echoing triggers.
- Healing-Reliant Lineups (Hard Counter) — Call of Death’s anti-sustain mechanic and echoing’s cascading damage overwhelm single-healer defenses, as every ally attack on echoing targets generates healing that outpaces enemy sustain.
- Sustained Damage Lineups (Soft Counter) — Lineups that deal damage slowly play directly into Chu’s strengths, giving him time to stack Resonance Mic ATK bonuses and accumulate Call of Death healing for the team.
- Low-HP Back-Row Carries (Soft Counter) — Fragile back-row heroes take devastating damage from Death Symphony’s initial AOE plus echoing’s cascading TAC DMG, often dying before they can contribute their own damage.
Rating
S Tier. Chu is a meta-defining AOE carry from Dimension X1 onward whose echoing mechanic creates exponential damage scaling when combined with allies who attack frequently. His Echo exclusive gear casting Death Symphony at round 1 immediately applies echoing to all enemies, and Call of Death’s team healing provides rare support value from a primary damage dealer. No other Vindicator AOE hero matches his sustained damage output and team utility combination.
