If you are baking cookies, and you are dumb and do some wrong things to the mixture, will it turn our right? Probably not, and will result in something different. That is what happenes with the alchemy. If you are doing a recipe, and have low int, you will screw up, creating something else.
However that was since removed, and will never be back.
Oh, and Lockeboy guy, luck
does affect if you learn things or not. You get
lucky. -_-
