Duration: 10 minutes, Concentration
Saving Throw: DEX halves damage
Spell Resistance: Yes
Description: An immobile, vertical curtain of whirling blades shaped of pure force springs into existence. Any creature passing through the wall takes 12d6 slashing damage, with a DEX save for half damage. If you evoke the barrier so that it appears where creatures are, each creature takes damage as if passing through the wall. Each such creature can avoid the wall (ending up on the side of its choice) and thus take no damage by making a successful DEX save. A blade barrier provides 3/4 cover against attacks made through it.
Leveling: At 7th level and each level above that the wall may be lengthened by another 50 feet, or the circle may be expanded by 5' wide. Also for each level higher, the blades do an additional 1d6 slashing damage.
