Certain rare spells, such as Silence Creature, may temporarily disable spells that require verbal components., SomaticIcon tooltip.pngSomatic: A somatic component is a measured and precise movement of the hand. You cannot cast spells that require this component if you cannot move causing arcane spell failure resulting in a ruined spell. Spells without a somatic component may be used with disregard to Arcane Spell Failure chance. Note - that characters make the same arm gestures for most spells in DDO, so you can't tell which spells require this component by watching your character's animations.

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 tick, 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 that is already inside one hostile Blade Barrier takes no further damage by entering another one.
    • If a Cleric casts two overlapping Blade Barriers, crossing both of them will trigger only two hits.
    • However, if there was space left between the rings, crossing both of them would trigger four hits.
    • Thus, a caster who puts additional Blade Barriers close to an existing one may accidentally reduce damage enemies suffer.
  • Enemy AI will not avoid persistent spells, so mobs can be forced to repeatedly cross Blade Barrier zones.
  • Damage boosts: Internally the damage is considered both slashing and untyped - thus it is affected by force 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.

  • Minor bug: There is a display bug that blade barrier may render very thin and be 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.
