An antifire potion provides slight immunity to a dragon's breath. When used in conjunction with an anti-dragon shield, it will provide complete immunity against dragon fire for six minutes. 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. It may only be used after starting Dragon Slayer.
Players will get a warning in their chatbox when the potion is about to wear off after approximately 5 minutes, 45 seconds: "Your antifire potion is about to expire." Then they will get another message when it has worn off, approximately 6 minutes in total: "Your antifire potion has expired." This allows you to keep track of how long you have until you have to drink again.
WARNING! Players should remember that an antifire potion alone will not fully protect them from dragonfire (players will get a message in their text box stating that they have been horribly burnt by the fire). The potion's protection is so slight that, when used alone, even a single dragon can cause extensive damage to the player from its breath. Only when the potion is combined with the anti-dragon shield or dragonfire shield will players be completely immune to dragonfire.
