I was gonna say the exact same thing that Johnathan Sullivan(the guy 3 posts above me) said.
Get the Vile Lair DLC, then go to Deepscorn Hollow(added by the DLC), and there's gonna be a fountain somewhere inside(I think you have to turn left twice since you come in. There will be a big pool of water with something that kinda looks like the Washington Monument, but don't mind it at first. At the left side of the room with the 'fountain' there is a vein, which you can mine to obtain a special kind of 'salt'. Use the salt on the 'fountain' and you'll be cured.
Oh yeah, The Escapist isn't your Twitter.
