Yugol's ichor consumable

I’ve found a new consumable called Yugol’s Ichor (in the shop of Yurrith). I think it’s a new one. I’ve read the description, but I’m not quite sure what this potion is all about. Can somenone tell me?

disables auras so you can get through Maggots trial to Crate

Ok !
Thanks (again) Gnomish .

Yeah, don’t take it just before you go to fight Morgoneth :smiley:

I drink it right before fighting Morgonet, thankfully not in his arena, lol
