Character |
Description |
|---|---|
|
Orlea
|
A top healer who keeps your team alive with retain-based healing and vulnerable stacks. She performs best in long Chaos runs and works especially well with exhaust teams to increase team-wide damage. |
|
Nine
|
A strong DPS who uses ignition rampage. He builds exhaust to deal massive damage. His defensive vanguard mode gives shielding. He is essential for Great Rift clears. |
|
Mei Lin
|
The best single-target damage dealer for the Passion attribute. She easily applies weakness debuffs and gains AP from tenacity damage, allowing continuous combos. |
|
Sereniel
|
Uses AP very efficiently to spam laser attacks. Her multi-hit ravage triggers on-morph effects and helps save resources for supports. Very powerful in PvP. |
|
Narja
|
A healer and buffer hybrid. She converts cards into uniques (up to 80% of the pool). Provides defense buffs and necrosis-immune sustain. A key unit in Season 2. |
|
Veronica
|
Summons a ballista for extra damage and acts as a sub-DPS. Provides free damage and strong card draw power by drawing ally cards. Her 0-cost procs are very strong in short burst fights. |
|
Beryl
|
Focuses on spore burst damage. Retains attacks to upgrade them. Uses contaminated debuffs to enable one-turn kills (OTKs). Can work as either main DPS or support enabler. |
A-tier picks require a bit more setup than the S rank from this Chaos Zero Nightmare tier list. But they can deliver excellent results in their niches so A tier picks are also great for filling gaps in your roster.

It takes 20-40 minutes for full clears, depending on floors and RNG; optimize with AP gen for speedruns under 25 mins.
Narja's Gaya for DEF buffs will be ideal and Veronica's will be good for draw spikes. You can farm these via events for 20-30% power boosts.
