The main two things were:* Do heads have separate HP from the body? I ruled no, damage done to a head is also done to the body, but it doesn't carry over after a head is severed. This made the heads function like damage-soak minions?* Does regeration scale with Actual Number of Heads or with Original Number of Heads? I think RAW it should scale with Actual Number of Heads, but to keep things simple I kept it stable at Regen HP is equal to Head HP.
