Make a melee spell attack against a creature within range. On a hit, the target takes 5d12 lightning damage as lashings of electrical energy wrap around the target. At the start of each of the creature's turns they must make a Strength saving throw or be restrained until the start of their next turn. Creatures restrained this way may not meet the somatic requirements of spells.
At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d12 for each slot above 5th.
