> **Casting Time:** Action > **Range:** 60 feet > **Components:** V, S, M (a shard of ball and chain) > **Duration:** [[Concentration]], up to 1 minute You create a 20-foot-radius [[Sphere]] of powerful gravity centered on a point within range. **STR Saving Throw.** The area becomes Difficult Terrain for the duration. Each creature in the [[Sphere]] makes a STR Saving Throw. On a failure, the creature's Speed is reduced to 0 until the start of its next turn. **Repeated Save.** A creature must also make this save when the Sphere moves into its space and when it enters the [[Sphere]] or starts its turn there. A creature makes this save only once per turn. **Bonus Action.** On subsequent turns, as a Bonus Action, you can move the [[Sphere]] up to 20 feet in any direction. **Using a Higher-Level Spell Slot.** The sphere's radius increases by 5 feet for each spell slot level above 2. **Classes:** #Sorcerer, #Warlock, #Wizard
