Amatsu: Tsukikage has a special Skillchain property that enables him to trigger Cosmic Elucidation. This causes heavy damage to the whole party and results in automatic failure (expulsion from battlefield). He only does this after Meikyo Shisui, generally after a chain.
He does not "ready" his weaponskills, making them difficult to stun.
