A seeker may occasionally appear above the chaotic rift north of Draynor Village after the third week of the 2018 Hallowe'en event. The player will be alerted when the seeker appears with the following message:
Pestilence: Watch out for that Seeker's gaze! Collect some bile from my cauldron to blind it!
The seeker will rotate while firing a beam from its eye, damaging any players hit by the beam. The only way to damage the seeker is to throw vials of bile at it, which can be acquired from the cauldron near Pestilence. If not defeated in time, the seeker will explode, instantly killing any nearby players.
The seeker will initially take time to charge up its attack; during this time players cannot throw vials at it, and players will receive the message The seeker is still charging its gaze and cannot be attacked yet. If the seeker explodes instead of having its life points depleted, players will receive the message The seeker was not taken down in time and exploded everywhere!
The seeker begins using its powerful gaze on the area around the rift
The end result of the seeker's attack if it is not destroyed in time
