The Witcher

"Full Moon is an all-purpose potion. Witchers imbibe it before combat when they are not certain what kind of opponent awaits them. The downside to Full Moon is its high toxicity."

Full Moon potion significantly increases maximum Vitality. Specifically, it doubles the maximum total vitality.
