I understand the logic of making kirby's hats revert, the inhale ability is vastly overpowered as a result, but i feel kirby should be a DM responsibly NPC/boss. I also feel, if you really wanted to possitively dropkick someone with Kirby, you would send him in with a red/bronze Great Wyrm hat, not have him go into an encounter with a hat only to chain munch the Wizard, then Cleric, then the Melees.
