Creates a circular wall of flying blades which damages enemies that pass through them. The wall is centered on the caster at the time casting finishes. Enemies passing through Blade Barriers suffer 1d6 slashing damage per caster level. (Maximum damage 15d6 at caster level 15.) Duration is fixed at 30 seconds.

- Blade Barrier is not a damage over time effect, so if you cast it directly on top of a creature standing inside the blades (but not moving), it will suffer the first initial tic, but no further damage unless it moves out of the blade barrier.
- Blade Barrier only does damage to creatures as they transition from being within zero Blade Barriers to within one, or vice versa. A creature which is already inside one hostile Blade Barrier takes no further damage by entering another one. For example, if a Cleric 14 casts two overlapping Blade Barriers, a monster who runs across both of them will take just 14d6 + 14d6 = 28d6 damage (the same as if only one Blade Barrier had been cast). However, if there was space left between the rings, the monster would be hit entering and exiting both spells, for a total of (14d6+14d6)+(14d6+14d6) = 56d6 damage. Thus, a caster who puts additional Blade Barriers close to an existing one may accidentally reduce damage enemies suffer.
- Damage boosts: Internally the damage is considered both slashing and untyped - thus it is affected by force damage enhancements. Impulse/Impact items increasing damage of blade barrier as they increase: Force, Untyped, Slashing, Piercing, Bludgeoning. (see spell power)
- The slashing damage is only relevant for creatures who have special reaction to slashing damage, such as oozes that split.
Spell usable in Players versus Players, but not in brawls.
Like most persistent spells, will not function in water.
- As a side note: There is still a display bug that the display of a blade barrier may be very thin and difficult to see. If you look really hard, you can still see it faintly as if it is spinning much faster than it should be. This causes no change in its effectiveness, other than a little extra difficulty for the caster to properly space them out so as to not overlap them.
