The sacred artifact of the Brotherhood of Beerins' Fist, it is an old worn leather flask that depicts a monk kicking into the air. Inside is a genie, arguably the trapped Beerin himself. He looks grossly fat or emaciated, changing moment-to-moment between the two like they’re walking past fun house mirrors, and acts without a car in the world, though perpetually sloshed. He grants wishes that aim to humiliate one's enemies but makes the wish-maker promise to grant one of the his wishes in turn. The Flask is sometimes given to a worthy monk on a journey. The Flask of Beerin is also able to restore a monks Ki and small portion of health, but the flask must be kept at least 5 feet away from other magical drinks or they will be diluted and lose all magical property.
