I think i have a problem with my spells ..Earlier i was not able to cast things like strength boost 2 or dex boost 2 but can now but i now notice i have vigor cast but on no item and does wear off well not yet
Ok, I'm not sure about the others, but the I think the Vigor is being cast on you by a certain NPC in Fartown. It happenned fairly often to me while I was training there.
