BONES

You cause up to six bones to burst from places on the ground that you can see within range. Each bone has a diameter of 5 feet and a height of up to 30 feet. The ground where a bone appears must be wide enough for its diameter, and you can target the ground under a creature if that creature is Medium or smaller. The bones also act as an area of difficult terrain with a 10-foot radius that lasts until the duration.

If a bone is created under a creature, that creature must succeed on a Dexterity saving throw or take 1d6 bludgeoning damage. A creature can choose to fail the save.
