Updated for Version 2.7 - Cissia is the upcoming S-Rank Electric Attack agent from the Metropolitan Order Division. As a main DPS, she excels at applying Venom Mark to ignore enemy DEF for Electric and Physical DMG, building Venom stacks for powerful Serpent’s Venom Burst AoE explosions, and providing team CRIT DMG buffs via her Ultimate. Her banner drops in Version 2.7 (expected late February or March 2026). Pre-farming now ensures Day 1 readiness.
