Will-o'-Wisp Barrage

You create three tiny golden motes of light which flit about you and blink oddly. Each mote hits a creature of your choice that you can see within range. A mote deals 1d4 + 1 lightning damage to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several. If a creature dies as a result of this spell, the caster gains 1d4 temporary hit points for each dart that struck the target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more mote of light for each slot level above 1st.
