On a fail a magical rip appears in front of the target, a electric bolt zaps the target, the target takes 7d10 lightning damage, the target also must make a DEX save or drop whatever they hold. On a success they take half damage only. If the target is wearing metal armor they have disadvantage on the saving throws.
