Awaken Chaos Era | Wrathful Flood guide
Wrathful Flood's attacks
Strategies and team compositions
Bane Wraith is Water Affinity which means Wood will do +50% more damage and has a 50% chance when hit to take 50% less damage.
If you do not have a character with unhealable, bring heavy hitters, with one healer so you can out damage the boss's slow healing, while giving your team the sustain to do so. Zatlux, Evera, William, Savannah, and other wood-heavy hitters will be your go-to. Blackhorn makes an excellent sustain.
