Annozgoth's Vile Pulpit

You reconstruct a corpse you can see within range to become an unholy pulpit. All creatures within 15 feet of the must immediately succeed a constitution saving throw or take 6d8 necrotic damage, or half as much on a success. As an action on your turn, you can utter an arcane word to reactivate the pulpit, causing creatures within the space to repeat the saving throw. Alternatively, you can choose one allied creature to instead gain 5d8 temporary hit points, as your action.
