Elauria

You cause up to six pillars of stone to burst from the ground in visible locations within range. Each pillar is a 5-foot diameter cylinder, rising up to 30 feet tall, with AC 5 and 30 hit points. When a pillar is reduced to 0 hit points, it crumbles into rubble, creating difficult terrain in a 10-foot radius. If a pillar appears under a Medium or smaller creature, they must succeed on a Dexterity saving throw or be lifted by the pillar. If a pillar is obstructed by a ceiling, creatures on it take 6d6 bludgeoning damage and are restrained until they succeed on a Strength or Dexterity check against the spell's DC. Casting at higher levels allows for additional pillars.
