Amulet of the Gods

This simple amulet has a flat round surface where your deity’s symbol may be painted or etched. Once the amulet has been marked with a deity’s symbol, a cleric or paladin may attune it and use it as a spellcasting focus. 

This amulet has 6 charges. Once per turn, when you deal radiant damage to one or more enemies, you may expend up to two charges from this amulet and choose one of the enemies. The creature you choose takes an additional 2d8 radiant damage for each charge you expend. Additionally, choose one ally you can see within 60 feet of you. That ally regains hit points equal to 2d8 plus your spellcasting ability modifier. 

The amulet regains all expended charges daily at dawn. 

Notes: requires attunement by a cleric or paladin
