So is the preserved queen bee in the Vinewrath chest or not? The wiki says it is.
The item that actually drops is the Charged Quartz Orichalcum Amulet of the Hive.
The Preserved Queen Bee is the default upgrade in that amulet. I assume you extract it like you would any other upgrade component: with a salvage kit. Though with 1099g at stake, it had better be a Black Lion kit.
