New World Order

Dungeon Summary

Brutal D is weak to and and Confuse

Opens with a preemptive attack that does moderate damage and debuffs all stats. Recommended to buff up with mirrors using Zashiki so you can instantly reflect his debuffs to severely weaken him.
Uses attacks that can debuff and cause Taunt
Is assisted by various minions that will constantly respawn. The minions can buff Brutal D, break your shields, and attack/suicide bomb you for minor damage. If you defeat enough waves of minions, they will stop respawning.
- Soot: Applies a Counterattack Shield; will Suicide Bomb the Party.
- Gene P: Buffs the Stats of her allies; executes a Stab attack on the Party and self-destructs.
- War Head: Can wipe Shields; executes a 2x AoE Hit attack and self-destructs.
Once Brutal D is alone, he'll start using more powerful attacks on the Party; this is a good time to try and finish him off quickly!
Applying Confusion will cause Brutal D to attack his minions and himself. On higher difficulties, he'll deal moderate AOE damage to your team, and also heal himself and clear all his debuffs. Since Brutal D doesn't buff himself too often, it may be wise to avoid confusing him if you've already heavily debuffed him.
Upon his defeat, Brutal D will explode and cause minor to moderate damage to your team. His minions will also self-destruct as well (but cause no damage)
Overall a straightforward fight without any instant death mechanics or gimmicks

Cards such as Asmodeus, Colt, Fuujin, and Brynhildr are quite effective against Brutal D for exploiting his weaknesses.
AoE Enhance Cards such as Hestia, Undine, and Snow White are highly effective for dealing damage to Brutal D and his minions all at once.

The following cards can be exchanged for Points:

Fodder are Gas Cans. They give 2x EXP to all Event-related cards.
Aside from that, it's just straight EXP fodder.
