[2.7] Cissia Complete Build Guide

Rarity: S-Rank | Element: Electric | Specialty: Attack | Release: March 24, 2026 (Phase 2)

Overview

Cissia is an S-Rank Electric Attack DPS who doesn't just hit hard—she makes your whole squad's damage "weirdly higher" when you play her loop right. Her game plan: tag targets with Venom Mark, stock Venom, then let Serpent's Venom Burst do "set-and-forget" damage while the squad keeps swinging.

Why Cissia is Top Tier DPS

Team-wide DEF Ignore: Marked enemies take Electric/Physical hits with DEF ignore
Energy Regen Scaling: More ER = stronger DEF ignore on marked targets
Ether Veil Window: Ultimate opens team-wide CRIT DMG window
Flexible Playstyle: Works as Main DPS or Sub DPS
Boss Slayer: Excels in Shiyu Defense boss floors and Hollow Zero

Key Mechanics

Venom Mark + Serpent's Venom Burst

Multiple attacks tag enemies with Venom Mark
Build Venom resource over time
Auto-consumes Venom for Serpent's Venom Burst on steady rhythm
While Venom loop is running: Squad's Electric + Physical hits vs marked targets ignore DEF
DEF ignore scales harder with Energy Regen!

Serpent's Swiftness + Manual Cash-Out

Each Serpent's Venom Burst feeds Serpent's Swiftness stacks
Charged Attack: Spend stacks to supercharge lock-on dive
On-field: Rapidly burn remaining Venom for chain Bursts
Can hold Venom for buff uptime, then dump on demand for burst window

Ether Veil: Serpent's Eye

Ultimate reapplies Mark, refills Venom
Opens Ether Veil: Serpent's Eye for team-wide CRIT DMG window
Refreshing replaces old Veil
EX Special can be held to spend extra Energy for extra strikes

Skill Priority

Priority	Skill	Reason
1	Core Skill	Venom uptime + mark payoff for whole squad
2	Basic Attack	Most repeatable Mark + Venom generator + dive cash-out
3	Special Attack	Rotation glue, fast tagging, EX loads resources
4	Chain Attack	Big damage + Mark refresh + Venom refill
5	Assist	Emergency re-tag + defensive tempo
6	Dodge	Lowest impact on team value
