The values below reflect scaling with SP. There is no random factor.

BLIND: 30 sec CD, 5 to 10 sec duration,+/-2 secs from target's karma, does not exceed 10 secs, no post cast delay, 10 mana, 0 vigor
DAZZLE: 30 sec CD, 4 to 8 sec duration,+/-2 secs from target's karma, does not exceed 8 secs, no post cast delay, 10 mana, 0 vigor
HOLD: 20 sec CD, 3 to 6 sec duration, no post cast delay, 10 mana, 0 vigor
FA: Reduces hold by 0 to 20%, grants haste, grants 0 to 20 AGI.
EE: Reduces blind/dazzle by 0 to 20%, grants nightvision, grants 0 to 20 AIM.
Purge: Reduces power of enchantments by 0 to 50%, removes enchantments if power hits 0. 20 mana, 10 vigor.
Detect Invisible and Resist Poison: Only lose half power from purge.
Diminishing returns: If a second blind/dazzle is cast within 30 seconds, the target will only suffer half the duration and the timer is reset. A third cast halves the duration again and resets the timer. A fourth cast does nothing and does not reset the timer. Hold works the same but on a 20 second timer. This means that gang CCing a target will be fairly ineffective.
