Extended antifire(3)members

“3 doses of extended anti-firebreath potion.”

About this item

An extended antifire potion is a potion that provides slight immunity to a dragon's breath. When used in conjunction with an anti-dragon shield or dragonfire shield, it will provide complete immunity against dragonfire for 12 minutes (1200 game ticks) 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 may only be used after starting Dragon Slayer I.

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. Worth noting here: this item typically moves 17.75% in a day, which is more than the 10.30% you would be capturing — so holding it overnight risks more than the flip makes.
