The Witcher 2 potions

The potions in The Witcher 2: Assassins of Kings are different from The Witcher. They can no longer be consumed at any time and will last for a far shorter time than before.

To drink a potion, you must first enter the Meditate menu (not available during combat) and select the Drink Potion option. You can then select up to 3 potions to consume (4 if the Taster skill has been activated). The toxicity of selected potions cannot exceed 100 (the toxicity bar will turn orange and the potions will not be drunk). After exiting the meditation menu, the potions are immediately in effect. They are best to be consumed just before a fight.
