Hey guys! I’ve been grinding nonstop since cissia launched in  zzz's v2.7 second Half, and today I’m breaking down how to play this event to the fullest—and just how overpowered this agent is!

First off, cissia’s Gluttonous Evolution Frequency Tuning is absolutely game-changing! As an S-Rank Electric Attribute Attack Agent, she’s an all-rounder with both damage output and support utility. In combat, she accumulates Toxin to automatically apply Bone Erosion, dealing bonus Electric Damage and letting the entire team’s Electric Damage ignore a percentage of the enemy’s Defense. This is a nightmare counter against high-Defense bosses! Her Ultimate, Aether Veil: Cold Blood, is even better—it maxes out the entire team’s Crit Damage, turning Quick-Switch Burst Teams into absolute powerhouses!

cissia Summoning & Progression Guide

To unlock cissia, the Gluttonous Evolution Frequency Tuning is the only channel, available alongside Version 2.7 Second Half—don’t miss out! I topped up via COCODP Direct Top-Up before summoning, grabbing a small tier. I always use this for new agent summons, and the top-up speed has never let me down. For summoning, prioritize securing cissia herself; her core mechanics are pivotal, and she elevates Electric teams to a whole new level.

For progression, her skill rotation revolves around Toxin → Serpent Shadow → Bone Erosion. I recommend main stacking Electric Damage, Crit and Energy Regen to balance her damage output and let her charge her Ultimate quickly for team buffs. Always prioritize upgrading her Ultimate and Passive—these are the core of her support capabilities.

Best Team Comps for cissia

Based on official details and my hands-on experience, cissia pairs perfectly with Electric Disruption Teams. Here’s my top pick:cissia + Sid +Kira Buckland +Luciana de Montefio. cissia handles Defense reduction and Crit Damage buffs, Sid is the main DPS for high-frequency Electric Damage, Kira Buckland triggers Imbalance quickly, andLuciana de Montefio provides ATK Bonus and Coordinated Attacks.

This combo dominates every stage with ease.Here’s an alternative team:cissia + Jane + Nangong Yu + AmbyJane and Nangong Yu handle anomalies and Imbalance, cissia supplements damage and buffs, and Amby provides sustain.

This setup is rock-solid for both Trial of Conquest: Turbulence and Disaster Tide Task Force. P.S. If you summon cissia and want to pick up Sid too, remember to top up via COCODP—there’s a top-up rebate event going on right now, it’s a total steal! I’ve recommended this to tons of friends, and they all love it.

All in all, cissia is a must-pull for any Electric team. Her Defense reduction and Crit Damage buffs boost the entire team’s output by a huge margin. Take my word for it—don’t miss this event! Pair cissia with the Blazing Boil Sound Driver, and your Electric team will be fully built. Just go for it!
