You create 3 bolts of arcane energy, each of which targets a creature you can see within range. Make a ranged spell attack against each target. On a hit, a target takes 2d4 force damage, or 5d4 on a critical. Roll separately for each bolt. If you roll a 1 on an attack roll for one of the missiles, that bolt misses its target and blows up in your face, dealing all of the damage it would have dealt to you instead.

  At Higher Levels. If you cast this spell using a spell slot of 2nd level or higher, the spell creates one additional bolt for each spell level above 1st.
