You create one large missile of magical clay. The missile is a Large Construct with AC 7, 50 hitpoints, and immunity to poison and psychic damage. The missile remains in place until you use an action to launch it. When launched, the missile targets a creature of your choice within range. Once a target is selected, the missile flies up to 100 feet to reach the target. The missile may remain in the air for 5 rounds or until it hits its target or the target moves out of range. The missile also explodes in the air if it is reduced to 0 hitpoints. On contact with the target, the missile deals 4d8 + 6 Bludgeoning damage to its target. The missile then explodes, dealing 2d4+2 Force damage to every creature within 10 feet of the target, and you can cause all creatures affected by the explosion to have their speed reduced to 0 until your next turn.

Using a Higher-Level Spell Slot. The spell deals 1d8 more Bludgeoning damage and 1d4 more Force damage for each spell slot level above 4.
