Tigyrius's Stormstrike

Reaching towards the heavens you momentarily cause dark clouds to form or arcane fissures to open above you, from which three bolts of lightning lance downward at up to three targets of your choosing. Make a spell attack roll for each bolt, ignoring half and three quarters cover unless it is directly above the target. On a hit, the target takes 3d4 lightning damage.

Casting as a Circle Spell. You may summon 2 additional bolts for each level of spell slot contributed by the secondary casters.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, each lightning bolt deals an additional 2d4 damage.
