Lava Lamp

Shop
At the end of combat, Upgrade all card rewards if you took no damage.

Entering any room clears a flag. In a combat room the flag is set the moment enemy damage gets through your Block for at least 1 point (damage tagged unblockable does not count). When that fight's card reward is built, every upgradable card in it is offered already upgraded if the flag is still clear. It works in normal, elite and boss fights.
