A potion of heroism, also known as an adventurer's brew, was a magical concoction that was highly sought after as a temporary boost to one's abilities. Upon drinking, the potion fortified the imbiber's body, and for around an hour was magically enchanted 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.
