Question: witcher 3 what is decoction?
Answer: Decoctions in the Witcher 3: Wild Hunt are a type of alchemical product akin to Potions. ... Decoctions do not raise your toxicity level, but rather take up an amount of space on your toxicity bar. This means that decoctions cannot take advantage of certain skills in the alchemy tree (eg: delayed recovery, killing spree).
