Been waiting for this event outside of Almuten Estate in Gendarran Fields – some egg sacs should spawn, I crush them, and spawn this champ spider that I need to kill for her Enraged Spider Queen’s Venom
I’ve seen the event a few times over the years. I’ve been trying for HOURS a day waiting for it to spawn but no luck. I’ve tried guesting to lower pop servers in an attempt to get different maps.
I’m not aware of any pre for the event.
A youtube guide video for the collection also mentioned troubles with this event, saying that they had to wait till right after a patch hit to get the event. I think something’s bugging out and it’ll spawn once per map – and that’s it – never again.
