King of Tokyo
Does healing from any source, including cards, Power Up cards or healing in Tokyo, end Berserk mode?
Several players agree, and one key answer is relayed from the publisher rather than posted by it.
Yes. Any healing ends Berserk mode, including healing from cards and Power Up cards. A Monster in Tokyo cannot heal by resolving Heart dice, but it can still heal from cards, and that ends Berserk too.
