Blade Barrier

Casting Speed:

Fast as of update 9.

Notes:
 * 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.


 * Although Blade Barrier deals slashing damage, physical damage reduction does not apply to spells.


 * 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.

PVP:

Spell usable in Players versus Players, but not in brawls.
