As part of the casting of this spell, you throw a handheld object weighing 5 pounds or less. For the duration of the spell, you choose the object’s exact trajectory, up to 150 feet of distance. The object can navigate around obstacles and corners, and ignores half and three-quarters cover if it is directed at a creature. If the object strikes a creature, that creature must make a Dexterity saving throw or take 4d4 bludgeoning damage, or half as much on a successful save. The object stops moving after striking a creature or object.
