      This skill is very useful!05 Jul 2016 15:38  

      5/5 points = 100% resistence against vitality loss. So you can buff yourself with potions until your toxity maximum is reached anytime.

        I dont really understand this perk. Increase potion strength? Clearly doesnt increase max toxicity level since there are other perks that do that. If it has to do with taking potions while you are overdosing, well why would i ever let my toxicity level stay overdosed. it drains so much life.

          Maybe the worst skill in the game05 Jul 2016 15:38  

          This skill seems completely pointless. There are some skills of questionable usefulness that are at least a lot of fun to use, like the arrow deflection one, but this makes a small difference even when maxed. CDPR should also change how it's described since most people have no idea what the skill's meant to do and assume it's just a badly-worded reference to Toxicity.
