A cloud of smoke gathers around a creature of your choice that you can see within range and stimulate its natural healing ability. The creature regains hit points equal to 2d6 + your spellcasting ability modifier. This spell has no effect on constructs.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the healing increases by 1d6 for each slot level above 2nd.
