Tips and Tactics

  • If you are Shadow specced, you can deal an immense amount of damage with just Shadow Word: Pain and Devouring Plague.
  • As a disease, Devouring Plague cannot be dispelled by a Warlock's felhunter, which makes it an interesting option in duels..


  • It will do extra healing if you buff Vampiric Embrace.
  • It is worth mentioning that this spell is classified as a Disease, not as a magical debuff.
