      Why investing 5 points into this skill just to avoid damage from overdose?! You only need 1 point in the gourmet skill to get much more vit regeneration than overdose will ever drain. With doubling food effects from the rune smith you will get 160 vit regen "permanently".

        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.

            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.

              Currently its reported that this ability functions without being slotted, I'll test this out tonight if I can.
