Toro’s Shattering Boulder

You stomp your foot upon the ground and throw forth your hand, raising a boulder from the earth. Choose a point you can see within range that is an unoccupied space of solid earth. In this space, a 5-foot sphere of solid earth rises from the ground. This sphere has an AC of 15 and 30 hit points; it is resistant to slashing, bludgeoning, and piercing damage and immune to psychic and necrotic damage. The boulder remains floating in space for 1 minute or until detonated. To detonate a boulder created by this spell, you must spend your reaction to send a blast of pure arcane energy into the boulder. Fragments of sharpened stone rain upon Creatures within 10 feet of the detonated boulder; they must make a Dexterity saving throw. On a failure, they take 4d8 bludgeoning damage and 1d4 slashing damage from the shrapnel and have the Muddy condition until the end of their next turn. On a success, they take half as much damage and suffer no further ill effects.

Muddy is a special condition which grants disadvantage on attack rolls using either Strength or Dexterity, as the creature’s body is weighted down. Movement taken while under this condition is considered as if moving through difficult terrain.

Additionally, if you have this spell and the spell Toro’s Steppe prepared, you can further utilize the Muddy condition. As an action, you can cause the mud surrounding a creature to begin to harden. The creature must make a Strength saving throw to avoid this effect. On a failure, the creature becomes restrained.
