Enesstrere's Lightning Charge

You brandish the weapon used in the spell's casting and make a melee attack with it against one creature within 5 feet of you. On a hit, you deal the weapon damage as normal, and each target within 30 feet directly in front of you must make a dexterity saving throw against your spell save DC. On a failure the target takes 2d6 lightning damage, or half as much on a success.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 2nd.
