Im no coder, Im not even a hacker.
Recently, I've been experimenting with swf loaders from darkmystic/epicsauce and how cell/room joins affect shop loads. In fact this actually worked. I loaded an swf of an item with a quest , Ex : Primal Orb, I type it into darkmystic and bam it loads, I click it and the quest actually loads.
Possibly, AE has backup quests for any of these items while they removed the original ones, If we can find them, doesn't that mean the rares aren't "rares" ?
Just a theory.
TLDR Swfs pets with quests or weapons with quests are accessible if you load them through a trainer.
(Oblivion Blade, Crag/Bamboozle, Drudgen, etc)
