Limitation: One terrain type only, as specified when casting Feralborn.
At the start of each of your turns, you heal and regain that many HP. This does not consume your hit die. If you were dead due to MP loss, this brings you back to life. If you take fire damage, this effect doesn't apply on your next turn. You only die due to HP loss if you start your turn without successfully regenerating HP.
