> **Casting Time:** Action
> **Range:** Self (10-foot radius)
> **Components:** V, S
> **Duration:** 10 minutes
**Dimensions.** You cause a cage of cartilage and bones to erupt from the ground that surrounds a 10-foot-radius [[Emanation]] originating from you. The bones are thick and provide [[Cover|Three-Quarters Cover]] to creatures inside and outside.
**Entry.** When you or any other creature attempts to pass through the cage, you can use your [[Reaction]] to let them through. Large or Larger creatures cannot enter the cage, and are pushed to the nearest unoccupied space if they are within the cage's area when it first appears.
**Stats.** The osseous cage has AC 12, 100HP, Immunity to Psychic and Poison damage, and Vulnerability to Bludgeoning damage. If you cast this spell again while you already have a cage summoned, the previous cage turns to dust.
**At Higher Levels.** When you cast this spell using a spell slot of 4th level or higher, the cage has an additional 20 hit points for each slot level above 3rd.
**Classes:** #Druid, #Warlock, #Wizard
