Super antifire potion(4)members

“4 doses of super anti-firebreath potion.”

About this item

A super antifire potion is a potion made with Herblore that provides complete immunity to regular dragonfire for three minutes, as well as partially blocking the stronger dragonfire of Galvek and Vorkath. It may only be used after starting Dragon Slayer I. It can be made by a player with 92 Herblore by adding crushed superior dragon bones to an antifire potion, which grants 130 Herblore experience. With 98 Herblore, the super antifire potion can be upgraded to an extended super antifire with lava scale shards.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
