Until the spell ends, your body crackles with electricity, and you gain the following benefits:

• You are immune to lightning damage, as well as to the paralyzed and stunned conditions.

• When a creature hits you with a melee attack, it takes 1d8 lightning damage and can’t take reactions until the start of its next turn.

• You can use your action to create a line of lightning 15 feet long and 5 feet wide extending from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 4d8 lightning damage on a failed save, or half as much damage on a successful one.
