Scentless potion is made by combining an Argway herb and a Shadow vine in a juju vial of water. Both the ingredients and the finished product are untradeable. It requires 59 Herblore to make. Drinking this potion while trapping jadinkos will mask your human smell, simulating the effect of smoking all of your traps with a torch and increasing their effectiveness. The effects last for five minutes. Logging out will end the effects. Consider using in conjunction with Zamorak's favour.
