Description: A wall of thorns spell creates a barrier of very tough, pliable, tangled brush bearing needle-sharp thorns as long as a human's finger. Creatures can force their way slowly through the wall by making a Strength check as a full-round action. For every 5 points by which the check exceeds 20, a creature moves 5 feet. Attempting to move through a wall of thorns takes slashing damage per round of movement equal to 25 minus the creature's flat-footed AC. A creature forced into the wall takes similar damage. Creatures with the ability to pass through overgrown areas unhindered can pass through a wall of thorns at normal speed without taking damage.
A wall of thorns can be breached by slow work with edged weapons. Chopping away at the wall creates a safe passage 1 foot deep for every 10 minutes of work. Normal fire cannot harm the barrier, but magical fire burns it away in 10 minutes.
Despite its appearance, a wall of thorns is not actually a living plant, and thus is unaffected by spells that affect plants.
