Kami Z should use Fireball on the Assassin (or he'll kill someone else...).
Kami M should finish off the 9 Warriors.
Lampra should move to the Commander (there are exactly 22 squares there) and probably move back.
Ki should heal everyone.
Shram and Gonor should use their abilities...
Genza, I don't know, maybe break the wall with 4 archers.
Kami should taunt to prevent focusing on Shram.
Gonor should use Lightning Strike to finish them off.
Gena should break the wall with the Siphon ability, although it's not that important. But since Shubulla is a much worse opponent than his father, Gena will definitely be targeted by the Siphon from invisibility, so the 9 is the biggest threat to him.
I agree with Lampra, Kamistelle, and Ki.
Waiting for Lok for a third opinion.
