The Witcher 3: Wild Hunt · Consumable
Wyvern Decoction Decoction
Wyvern Decoction increases Attack Power with each landed blow, until combat ends or Geralt takes damage. It requires Wyvern mutagen, Celandine, Dwarven spirit, and Moleyarrow; its diagram is obtained by completing the Contract: Patrol Gone Missing at the Nilfgaardian Army Group Center Camp.
What to consider
Taking damage ends the Attack Power buildup before combat ends.
