2nd-Level Evocation
Up to six creatures of your choice that you can see within range each regain hit points equal to 2d8 + your spellcasting ability modifier. This spell has no effect on undead or constructs.
When you cast this spell using a spell slot of 3rd level or higher, the healing increases by 1d8 for each slot level above 2nd.
