The quest Stonefather’s Boon in Deepholm is still bugged, I have been checking it daily. This quest is part of the critical path, and not being able to complete it is gatekeeping a large portion of the zone.
I know there’s a work-around to use the item from the pillar, but that won’t suffice for a launch scenario as it takes even a single person a long time to complete it due to the 3 minute buff duration. The item needs to be fixed or the buff duration set very low.
