Bouncing Surge

A spear of crackling yellow energy shoots out from your hand towards a creature within range. On hit, the creature takes 1d12 lightning damage. Each creature within 10 feet of the original target must make a Dexterity saving throw or take 1d6 lightning damage. When casting this spell with a level 4 or higher spell slot, this spell does 1d12+3 lightning damage, and the AoE effect does 1d6+2 damage.
