Sorry, what I meant to say was that the stone jumps me way higher than I used to see it do. After one use, the stone now jumps me from the base 50% corrupted I have for all my attributes all the way up to something like 90% corruption. I only used to see these levels after using the stone two or three times. My guess is it is getting me up to that 75% new baseline my character is at and then adding tainted on top of that to give me the temporary debuff.
