:Gadwall helps a witcher's mutated body regenerate much faster than usual. No wonder witchers often consume it when preparing to fight especially powerful beasts. Gadwall is a stronger version of the Swallow potion. As Gadwall courses through the veins, however, it burdens a witcher's body, causing him to deal less damage and lose Vigor at an accelerated rate. These side effects can be reduced by drinking the Rook and Tawny Owl potions.
:Potion significantly increases Toxicity when imbibed.
:Gadwall is recommended before long fights. Its slow but constant regeneration of Vitality provides its user with an advantage over opponents..
