What is the go with the Purity Perk for alchemy? I have maxed out my alchemy skill to 100 and perked a trail to Purity, but cannot select it. Do i have to have "ALL" previous perks?????
You have to put a point in Experimenter first if you take the left branch. Known bug. I bet there's a mod kicking around to fix it as it's an easy fix; if not it will be in the first USKP.
