Extended antifire

An extended antifire potion provides slight immunity to a dragon's breath. When used in conjunction with an anti-dragon shield, dragonfire shield, Protect from Magic, will provide complete immunity against dragonfire for exactly 12 minutes per dose (48 minutes per 4-dose potion). Antifire potions are especially useful against metal dragons and the King Black Dragon, though only when combined with other said forms of protection.

It can be made by a player with 84 Herblore by mixing a regular antifire and Lava scale shards, which grants 110 Herblore experience. One dose is created per shard, so four shards will be needed to create a four-dosed extended antifire. Players with at least 91 Herblore can mix caviar into a 2-dose Extended antifire mix.

Players will get a warning in their chatbox when the potion is about to wear off: "Your resistance to dragonfire is about to run out". Then they will get another message when it has worn off, approximately 15 seconds after the initial warning: "Your resistance to dragonfire has run out". 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.

Drinking an antifire can protect players against the effect of enchanted dragonstone bolts' special effect. Again, players will get a message in their text box stating that they have been burnt/horribly burnt by the fire, although the damage dealt will range only from 10-12 hitpoints.
