Electric Current F

You release a powerful current of lightning into a 15 foot cone originating from you. Creatures caught in the cone must succeed on a dexterity saving throw or take 3d12 lightning damage and have their AC reduced by 2 until the start of your next turn. Upon success a creature takes half damage and suffers no additional effect.

At Higher Levels. The spell's damage increases by 1d12 for every slot level above 3rd.
