Use the Wicked Strong Fetish to curse 5 buildings or towers in Bladespire Hold and 2 in Bloodmaul Outpost. Return to T'chali the Witch Doctor at Bloodmaul Ravine in the Blade's Edge Mountains after you have done so.
5x Bladespire Hold building cursed
2x Bloodmaul Outpost building cursed
T'chali wants revenge on all of the ogres!
T'chali was a powerful witch doctor in life. If you reach into me grave you will find a wicked strong fetish.
Invoke the fetish's magic at the entrances to the buildings and towers of both Bladespire Hold and Bloodmaul Outpost. The voodoo you work will summon an evil spirit that you must defeat. This in turn will curse that building.
Beware, if you attempt to curse a building that is already cursed, you will call down another cursed spirit!
