Potions of heroism, also known as "Adventurer's Brew", were magical concoctions that temporarily boosted the abilities of Mortalborn. Upon drinking, the potions caused a Transmutation that, for around an hour, allowed them to perform slightly better at any task they attempted.
Though expensive to produce and rare to find, potions of heroism were some of the most sought-after consumables by adventurers, who relied on the boost to their abilities for myriad tasks.
