Air crystallizes into a throwing glaive in your hand. As an action, you can throw the glaive up to 50 feet away. Choose one target and a point no more than 10 feet away from the target. The target must make a Dexterity saving throw, taking 4d6 slashing damage on a failed save or half on a successful save. Whether or not the attack hits, the glaive moves towards the point and explodes in a 5 foot cube, dealing 1d4 bludgeoning damage to a target in that area. After making this attack, whether or not the attack hits or deals damage, the glaive dissapears.
