> **School:** Conjuration, Osteomancy > **Casting Time:** Action > **Range:** Self > **Components:** V, S > **Duration:** 10 minutes You cause cartilage and bones to erupt from the ground, forming a cage surrounding a 10-foot-radius [[Sphere]] centered on you. The bones are thick and provide [[Cover|Three-Quarters Cover]] for creatures inside and outside. **Entry.** Creatures, including yourself, can’t pass through the cage unless you take a [[Reaction]] when a creature attempts to cross to let it through. A Large or larger can’t enter the cage and is pushed to the nearest unoccupied space if it is within the cage’s area when it first appears. **Stats.** The osseous cage has [[Armour Class|AC]] 12, 100 [[HP]], and Vulnerability to Bludgeoning damage. If you cast this spell again while you already have a cage summoned, the previous cage turns to dust. **Using a Higher-Level Spell Slot.** The cage has an additional 20 [[HP]] for each slot level above 3. **Classes:** #Druid, #Warlock, #Wizard
