3rd-Level Evocation
As you call out words of restoration, up to six creatures of your choice that you can see within range regain hit points equal to 1d4 + your spellcasting ability modifier. This spell has no effect on undead or constructs.
When you cast this spell using a spell slot of 4th level or higher, the healing increases by 1d4 for each slot level above 3rd.
