FINALLY beat that mofo, Reimu 215. Heavily customized my gear to maximize my defenses, and finally properly executed my strategy. I used Ran/Iku to buff up my Nukers, mainly keeping those that were fragile (Kaguya, Suwako) out of harm's way for the first half of the battle while my slower/tougher nukers (Youmu, Patchy) slowly damaged him until he got right before the breaking point. I abused Reimu also for the buffs to maximize my defenses going into the final portion where I knew I would not have time to buff. Another thing to note: I had Aya at like 80% SPD buff going in also, so that she could help me guys jump in and out and lightning speed, increasing their lifespan in the face of the steadily increasing speed and power of the boss.
In the end, the boss used a couple silence clouds while in berserk mode (yay!) and Suwako/Kaguya among others wreaked havoc with full buffs and SPD buffed switchers getting them in and out. I sacrificed some of the now useless characters (Iku, for example) to soak a hit in the first slot and save Meiling's HP for the later more dangerous hits. From there, I ended up beating him with a good part of my party left alive. Ironically enough, this was the one battle where I had someone sniped at the beginning (double slash to 3rd Rank Alice killing her). 18F was a champ as usual, starting off the berserk mode with Military Rule and then managing to survive the entire onslaught, assisting in switching my nukers in and out. Thank god that boss is dead :V
TL;DR;
Baal Avatar finally dies; may he rest in pieces
