You create a massive Rampart of hard-packed earth and stone 5 feet thick. The Rampart cannot be conjured so that it occupies the same space as another Creature or object. Each 5-foot-wide section of the Rampart has hardness 0 and 180 Hit Points. A section of the Rampart whose Hit Points drop to 0 is breached. If a Creature tries to break through the Rampart with a single attack, the DC for the Strength check is 60. A Creature can climb over the Rampart with a DC 20 Climb check.
