+324 Crit Rating & Chance on dealing spell damage to gain 30% spell haste for 10 seconds.
Rewarded from the Black Prince questline. Obviously since it's datamined, this could end up being a delete-worthy thread. But... depending on length of the ICD, this could be a pretty sick meta for us Affliction 'locks.
Edit: Updated with duration of buff.
Edit 2: Changed Stamina -> Crit Rating
