Seftonium

Despite being made of so many ingredients as to make its origins near impossible to deduce, the small edible ball of seftonium is reportedly very tasty. When eaten, it will reset any class switch cooldown. Neither specifically a herb, mineral, nor curative at all, seftonium first became available during Mayaween of 696 AF and can only be obtained via special promotions. Rumour has it that the opiate is named for an adventurer whose indecisiveness was legendary, quitting his class and taking up new ones successively each year.
