Dark Bullet

You point your finger at a target and a bolt of dark energy projects towards them. You make a ranged spell attack and on a hit you deal a d4 + your spellcasting modifier in necrotic damage and target takes a -2 to AC until your next turn as the bolt phases between the targets armour leaving weak points.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4) and 17th level (4d4).
