how long does a antifire potion
Antifire potions are especially useful against metal dragons and the King Black Dragon, though only when combined with an anti-dragon shield or dragonfire shield. It doesn't work when used with Protect from Magic alone. The potion lasts for exactly 6 minutes per dose (24 minutes per 4-dose potion) It can be made by a player with 69 Herblore by mixing clean lantadyme and then dragon scale dust in a vial of water, which grants 157.5 Herblore experience.
