Lycanthropy

Lycanthropy is an ability in Heroica Advanced used by Werewolves and The Dark Druid. If you roll Skull in combat with a monster with Lycanthropy, roll again. If you roll Skull again, you become a Werewolf if you survive the battle. Switch the hero's piece with that of a werewolf's. Only switch back to the original hero if you are healed by the Druid, drink a Life Potion, or defeat the Dark Druid. Even if you do not roll skull a second time, you still take damage.
