Cissia
Cissia is a top-tier Electric Attack powerhouse with unique mechanics that enable massive DEF ignore for the entire squad. She offers incredible flexibility in team compositions and provides significant utility alongside high personal damage output.
Cissia operates through a unique 'Venom' mechanic, which she gains upon entering the field and accumulates via various skills to trigger extra 'Corrode Bone' Electric DMG instances. Her playstyle centers on managing this resource to maintain squad-wide DEF ignore and CRIT DMG buffs, which are amplified by her Core Passive and Additional Ability. By utilizing her 'Serpent's Kiss' and EX Special Attack, players can maximize her damage potential while maintaining high uptime on team support effects. She effectively serves as a carry that rewards technical execution and energy management.

Energy Regen
CRIT Rate increases by 25/28.8/32.5/36.3/40%. When the equipper consumes at least 20 Energy in a single instance, every 20 Energy consumed grants 3s of a buff: when dealing Electric DMG, ignore 28/31.5/35/38.5/42% of the target's DEF. Repeated triggers extend the duration, up to a maximum of 30s. When entering combat, gain 10s of this buff. While the equipper is not the active character, the duration no longer decreases.
Why it works —Provides optimal CRIT Rate and essential DEF ignore uptime for Cissia.
Energy Regen
Increases CRIT Rate by 20/23/26/29/32%. When the equipper triggers an Aftershock that deals Fire DMG, their attacks ignore 15/17.2/19.5/21.7/24% of the target's DEF for 8s. Can stack once every 3s, up to 2 stacks. Repeated triggers reset the duration.
Why it works —Provides optimal CRIT Rate and essential DEF ignore uptime for Cissia.
CRIT Rate
Increases CRIT Rate by 15/17/19/21/23%. When the equipper deals DMG with a Basic Attack or EX Special Attack, they gain 1 stack of a buff. Each stack increases the equipper's Electric DMG by 12.5/14.5/16.5/18.5/20%, up to 2 stacks. Each stack lasts 40s. The duration of each stack is calculated separately. Can trigger once per use of a skill. At 2 stacks, the wearer's Basic Attack and Ultimate DMG ignore 20/23/26/29/32% of enemy DEF.
Why it works —Provides optimal CRIT Rate and essential DEF ignore uptime for Cissia.
ATK%
CRIT DMG is increased by 30/34.5/39/43.5/48%. When the equipper lands a hit with a Basic Attack, Special Attack, or Aftershock, they gain 1 stack of a buff. Each stack increases the equipper's CRIT DMG by an additional 10/11.5/13/14.5/16%, stacking up to 3 times. The effect lasts for 30s, with each stack's duration calculated separately, and can only be triggered once per use of a skill. With all 3 stacks, the equipper's Electric DMG increases by 20/23/26/29/32%.
Why it works —Provides optimal CRIT Rate and essential DEF ignore uptime for Cissia.
