The Witcher Potions - Full Moon
This potion significantly increases maximum Vitality.
Full Moon is made by mixing ingredients providing two measures each of vermilion and hydragenum, and one measure of quebrith; strong, top quality alcohol must be used as a base.
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.
