Wisps of darkness form a solid blade in your hand that remains for the duration or until it leaves your hand. The blade functions as an off-hand swift weapon with the finesse property that deals 1d6 damage. It deals 1d6 extra damage when you get a success on an attack roll against a target in an area obscured by shadows or darkness. When you cast this spell, you can make an attack with the blade created by this spell.
