Στο παιχνίδι για υπολογιστή The Witcher 2: Assassins of Kings[]
In The Witcher 2, projected toxicity is shown during Κάνει διαλογισμό as Γκέραλτ imbibes Φίλτρα. The total level of toxicity increases for the duration of each potion consumed, effectively limiting how many may be active at once. The least toxic potions have a toxicity of 25 and the most toxic have a toxicity of 50. Γκέραλτ cannot consume potions if their combined toxicity exceeds 100, a visual indicator is the toxicity bar turning orange for invalid combinations.
