[edit] Description
Blackout is a Priest talent that has a chance to stun an opponent for 3 seconds. Blackout triggers from damage spells from the Shadow tree, but not from Shadow spells in the Discipline tree (such as Mana Burn or Feedback). It does 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 depends on the number of talent points invested, increasing by 2% for each point, up to a maximum chance of 10%. This talent is usually taken by PvP Shadow Priests in lieu of Spirit Tap.
