Magic Blackout Stunned. Duration: 3 seconds

Blackout was a priest talent that has a chance to stun an opponent for 3 seconds. Blackout triggered from damage spells from the Shadow tree, but not from Shadow spells in the Discipline tree (such as [Mana Burn] or Feedback). It did not trigger off spell ticks (such as each tick of [Shadow Word: Pain]), only at the initial hit of the spell. The chance to trigger depended on the number of talent points invested, increasing by 2% for each point, up to a maximum chance of 10%. This talent was usually taken by PvP Shadow Priests in lieu of [Spirit Tap].

Notes

• Blackout could trigger off priest racials like [Shadowguard] and [Touch of Weakness].
