Astral Bomb

Summons a star-shaped projectile that moves in a straight line towards the desired location. If the projectile hits an enemy or obstacle in its path, it explodes, dealing 6 (2d6 + 1) Force damage to all creatures within a 20 ft. radius. If the projectile makes it to the desired location, it will float there until it is damaged or dispelled. If it is damaged at all, the projectile will explode, forcing all creatures within a 30 ft. radius to make a DC 16 Dexterity saving throw. Upon a failure, the creature takes 8 (2d8 + 1) Force damage. Upon a success, the creature takes half the amount.
