Whenever you finish a Long Rest, choose Acid, Cold, Fire, Lightning, or Poison. When you cast a Cleric spell or use a Cleric feature that deals Necrotic or Radiant damage, you can change that damage to the chosen type.
Once per turn when you deal damage of the chosen damage type to a creature, you can deal extra damage of that type equal to your Cleric level to that creature. You can deal this extra damage a number of times equal to your Wisdom modifier (minimum of once). You regain all expended uses when you finish a Long Rest.
