Antifire

An Anti-fire potion provides slight immunity to a dragon's breath. However, when used in conjunction with an anti-dragon shield it will provide complete immunity against dragon fire for exactly 6 minutes. It can be made by a player with 69 Herblore by mixing lantadyme and ground blue dragon scale in a vial of water, which grants 157.5 Herblore experience. Players will get a warning in their chatbox when the potion is about to wear off, then they will get another message when it has worn off, with approximately 15 seconds interval between the two. Anti-fire potions are also useful especially against metal dragons and the King Black Dragon, though only when combined with an anti-dragon shield.

WARNING! Players should remember that an anti-fire 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). Only combined with the shield will players be completely immune to dragonfire (for 6 minutes).
