Fuck Black Flame. Pyromancy is for pussies, anyway.
You start the fight by throwing the LT to your victim, then you eat the GB, and be ready to use some Humanities if your adversary heals or if you are in a 2vs1 or 3vs1.
Finally, the BPMC are there in case of toxic or poison statuses, and the RP if your opponent tries to fuck up your Zwei.
