Okay, so I was doing the quest to get the Elven Funerary Stone for that lady in Tarant and while I was inside the tomb, while I was making space for the stone, my character started losing half of his fatigue and getting poisoned for about 100 points ever 20 seconds or so. Virgil kept healing me and removing the poison but this kept happening. I tried reloading a my save after picking up the tomb, turning off the game, putting the tomb down, nothing worked. I checked my curse screen too and it said I didn't have any curses yet. I dunno if this is a part of the game or a bug but I kind of can't do anything anymore without falling over from not having any fatigue. It's pretty early in the game so I don't mind making a new character however it's pretty annoying and was wondering if there was a way to stop this.

Sounds like you equipped a cursed item, such as poisoned leather armor or boots of the dark toll. Remove all armor if you want to be absolutely sure :)

I feel like a noob now. Yep, picked one up in a chest. Thank you.
