Super antifire

Super antifire potions can be made by players with at least 85 Herblore by mixing a 3 dose antifire potion with a desert phoenix feather. Making this potion grants the player 210 Herblore experience. Each dose of super antifire lasts for 6 minutes.

The potion will render the player completely immune to dragonfire, unlike the regular antifire potion which requires a wielded dragonfire shield or an anti-dragon shield to bestow complete immunity. This allows for the player to use a two-handed weapon or use a different shield, god book, defender, etc.

Before a player's potion effects run out, a message will appear saying, "Your resistance to dragonfire is about to run out."

Caution: If this potion runs out, you can be hit for 500+ damage! Re-drinking this potion as soon as the message "Your resistance to dragonfire is about to run out" appears is highly recommended (in case of lag, etc.)

This potion is not tradeable and players cannot use the Assist System to make it therefore players must have level 85 Herblore in order to make it, unless you use boosts, in which case you only need level 79.

Making super antifire potions is a relatively inexpensive way of training Herblore after level 85 because although the potions are untradeable (none of the production costs can be recouped), the only ingredient which can be bought is the antifire potion, which is the only production cost. Phoenix feathers are untradeable and must be gathered by the player themselves. If they have a high Thieving level, using the Eagle transport system, it is possible to collect over 1000 per hour. This is enough for 210,000 herblore experience (a faster method would be to use the imp-in-a-box method, in conjunction with a broomstick, and running through Shantay Pass).

It would then take a further 30 minutes or so to make those 1000 potions, which would bring the hourly experience rate down to about 150k. This is over 2 times slower experience than adding crushed nests to toadflax potions (unf) to make Saradomin brews; However, super antifire potions cost less per experience point. If considering the cost savings, it is reasonable to value each desert phoenix feather at 1000 coins, effectively making the collection of these feathers en masse give the player over 1 (theoretical) million gold per hour toward Herblore training.

Flask
This potion can be made into a Super antifire flask by using at least six doses of it with a Potion flask. Players do not need a specific level to turn potions into flasks, but since all untradeable potions must be made by the player, the flasks actually have the same level requirement as the potion itself. It also makes you bring less super antifire potions than a 4-dose potion.

Production costs
The data in this table is based on the Grand Exchange prices of the potion's ingredients. It is accurate assuming all tradeable ingredients are bought off the Grand Exchange.

Practical use
The super antifire potion allows its user to wield a two-handed weapon against a dragon without the risk of high damage by dragonfire. This allows for dragon-killing with a weapon such as a Zamorakian spear, which would result in faster kills because of its high stab bonus. The super antifire is also useful for trips to the King Black Dragon, as the user would be able to safely wield a weapon such as a godsword. It also allows for using Korasi's sword together with a dragon defender. Compared to the Zamorakian spear, this setup has the same attack bonus and a strength bonus higher by one, while being less expensive. This potion can be used in wilderness, to counter dragon bolts (e) or before entering King Black Dragon's Lair. It also allows you to use Magic-boosting shield-slot items such as God Books, the Mages' book or the Arcane Spirit Shield for faster kills with magic on Metallic Dragons.
