Kyouko

Brainsplitter for damage opportunities, master thief in case that skill actually does something, and she ends up stealing some loot. Hailstorm is there to proc torpor constantly. Might not work so well if the ceiling is really low, tho.

Tries to dispatch annoying chaff first, then whatever is left.

Immune to a bunch of stuff thanks to the Intervention augment (petrification included, fk you cockabitch), also immune to sleep, and possession (no eepy death, no Wyrm NTR).
