Each creature in the line must make a Dexterity saving throw. A creature takes 6d6 lightning damage on a failed save, or half as much damage on a successful one. the target creature takes 10d6 lightning damage and must make a dexterity saving throw or the weapon they are wielding or another small object you can see (an instrument, a book, a gem, jewellery etc, NOT armour) is teleported to Thunars Gale for as long as you concentrate on the spell or until dispelled.
