Demon Tongue

Demon Tongue

RareIronclad
The first time you lose HP on your turn, heal HP equal to the amount lost.

The first time each turn you lose HP during your own turn, Demon Tongue heals the same amount back. Only damage that gets through counts, and only on your side of the round, so enemy attacks never trigger it. The check resets when your turn begins. Self-damage cards use the same damage path, so the loss is refunded at once. It is an Ironclad Rare, unlocked by Snuffed.
