You point your finger upward and utter a curt shout. Immediately, a pillar of rock explodes upwards from the ground.

Each round as a standard action, you conjure a pillar of rock anywhere within range. A creature standing atop the pillar will take 4d6 damage, Reflex negates, and will be knocked prone for one round if they fail their save.
