The caster directs a small, sparking mote of arcane energy toward a creature they can see within range. If the creature is friendly, it regains 1d4 hit points. If the creature is hostile, it must succeed on a Dexterity saving throw or take 1d4 radiant damage.
Healing or damage increases by 1d4 at levels 5, 11, and 17.
