Notes

• The "glow" effect is the same as on Unholy Weapon, i.e. small green skulls flying around the weapon

• Black Magic lasts for 10 seconds.

• Has a 35 second internal cooldown.

• Only procs for caster direct damage spells. "Physical magic" (paladin Hammer of Righteousness) and DOTs will not proc this.

• Exceptions to the "Physical magic" are the Feral Cat Form abilities Mangle and Shred. Also, Dire Bear Form with Infected Wounds will proc the enchant with Mangle and Maul. ^[1]

• Proc rate approximately 35%.

• Patch 3.3.0 (08-Dec-2009): This enchantment now sometimes increases haste rating for the caster rather than inflicting the caster's target with a damage-over-time effect. It is also now triggered by landing any harmful spell rather than inflicting damage with a spell. 
  
• Patch 3.0.8 (2009-01-20): Materials changed from 25 Infinite dust, 15 Greater Cosmic Essence, 10 Abyss Crystals to 6 Greater Cosmic Essence, 6 Dream Shard, 6 Abyss Crystal. 
  
• / Patch 3.0.2 (14-Oct-2008): Added.
