You bless a bottle of holy water through divine prayer, imbuing it with protective vitality. Choose up to four willing creatures within reach. Each creature that drinks from the holy water as part of the casting gains 2d8 + your spellcasting ability modifier temporary hit points for the duration, or until depleted. Creatures must drink as part of the casting; they cannot drink it later to gain the effect. If less than 4 creature drunk from it, the remaining liquid becomes mundane water. Undead and fiends that attempt to drink the holy water instead take 2d8 radiant damage, as the divine blessing scorches their unholy essence. This spell has no effect on constructs.
