Wall of Swords
Battle ATTACK4

Area A line, 20 yards long, 5 yards high, and 2 yards wide originating from a point within long range

Duration 1 hour

A wall of slashing swords forms in the area and remains for the duration. It totally covers everything behind it. When the wall appears, everything in the area takes 5d6 damage. A creature takes half the damage with a success on an Agility challenge roll. Creatures can move through the area, treating it as difficult terrain. When a creature enters the area from outside, or if it is inside the area at the end of the round, it must get a success on an Agility challenge roll or take 3d6 damage.
