I understand that this is pretty un-important as it has almost no use but I will post regardless since it fits. The Wabisuke modify affect for Ganju at lvl 50 (heal by 25% of attack at the end of each round) does not work for him. I got the zanpakuto up to lvl 50 the other day and the only health regain I received was from "revive" enchantment on my weapon. I tried taking this enchantment away as it may have impeeded with another souce of healing but the problem persists
Edit: My mistake. It does work. It just happens at the end of the round and not after Ganju moves
