Bones of the Earth (Alt) (HB)

You cause up to two pillars of stone to burst forth from places on the ground that you can see within range. Both pillars are cylinders with a diameter of 5 feet and a height up to 30 feet. The ground where a pillar appears must be wide enough for its diameter, and you can target ground under a creature if that creature is Medium or smaller. Each pillar has an Armor Class of 5 and 30 hit points. If reduced to 0 hit points, a pillar crumbles into rubble, creating an area of difficult terrain with a 10-foot radius. This rubble lasts until cleared. If a pillar is created under a creature, that creature must succeed on a Dexterity saving throw or be lifted by the pillar. A creature can choose to fail the save. If a pillar is prevented from reaching its full height because of a ceiling or other obstacle, any creature on the pillar takes 6d6 bludgeoning damage and is Restrained, pinched between the pillar and the obstacle. A Restrained creature can use its action to make either a Strength or Dexterity check against your Spell save DC. On a success, it is no longer Restrained and must either move off the pillar or fall off it.

At Higher Levels: If you cast this spell with a spell slot of 5th level or higher, you create two additional pillars for each slot level above 4th.
