Force Lightning

Effect

As an Action, you unleash a torrent of crackling dark energy in a 30 ft line or a 15 ft cone (your choice) originating from you. Each creature in the area must make a Dexterity saving throw (DC = 8 + your Proficiency Bonus + your Wisdom modifier). On a failed save, a creature takes 4d6 lightning damage + your Proficiency Bonus + your Wisdom modifier; on a successful save, it takes half as much damage. Creatures that fail the save cannot take Reactions until the start of your next turn. Targets may use reactions that reduce or negate damage before making the saving throw.
