Warrior nekker blood is dropped by nekker warriors upon their slaughter.
- A bug can occur in the game that causes the substance to disappear from Geralt's inventory. Although during the quest Lilies and Vipers, while in the forest section in chapter 3 there is an underground cave where you can find Nekker Warriors.
- Since this quest is only available for those following Roche's path, you may find this mod useful (it allows the player to add wanted items into merchants inventory), you can also acquire the Queen endrega's pheromones this way.
