After fighting a bunch of unique monsters in the Scintillating Caverns, I tried to rest off my remaining debuffs, but one of them is a cross-tier effect which is lingering around... and its duration is infinite!
Or use a Wild Infusion Physical. That should cure it, though considering it's buggy, no guarantees.
Edit: Missed that you were stuck on the map, so challenge mode is a nope. So if you've got a Wild Infusion on you, great. If you're Shaloren and didn't pick one up... Cheating time or start it all over.
I'm not crying. I'm offering a sacrifice to DarkGod in hopes he'll show favor to me.
