Do you guys know?


Edit* I've looked it up in google and I don't even know if its possible. If I got it in some weird way/bug I will throw it away

 

Nothing unusual, PO2 is OP

 

you can get those from lootbags, normally they are on items but you can get the enchantment off with the disenchanter

 

What kind of loot bag? I would assume its the legendary one...I kinda want to get a bunch of em

 

no reward from reward bags from HQM

 

ahh cool!
