Desert Bastion (3.5e Maneuver)

''The wind howled as a dark wave of sand blotted out the view. Those who attempted to push through came out as flayed skeletons on the other side.''

You conjure a vertical wall of abrasive sand that blocks the path and proves hazardous to pass through. You can make the wall as thin as 5 feet thick, which allows you to shape the wall as a number of 10-by-10-by-5-foot blocks equal to twice your initiator level. The wall cannot be conjured so that it occupies the same space as a creature or another object. The wall blocks line of sight and line of effect, and stops any ranged attacks moving through it, including ray attacks. Siege weapons and other unusually large objects pass through normally. Creatures can attempt to move through it, but movement is difficult and requires a full-round action and a strength check. A creature moves 5 feet through a wall for every 5 points their strength check exceeds your initiator level. When they enter the sand wall and each round they remain inside of it, they take 5d6 points of magic slashing damage from abrasion.

Creatures within the wall are considered blinded and deafened, and must hold their breath or suffocate. Spells with verbal components cannot be cast in the wall, while any other spell requires a Concentration check (DC 20 + spell level). Creatures with sufficient reach can attempt to attack through the wall, but targets have total concealment and total cover, and the attacker must target the correct square.

Any unprotected flame placed inside the sand wall is immediately extinguished. You may only have one instance of this maneuver active at one time, a second use causes the first to end.

This maneuver is a supernatural ability.
