The Foul Potion is the most context-sensitive item in the game.
In combat, it deals 12 damage to all enemies.
At a real merchant, throw it at the shopkeeper to receive 100 gold (with a slime impact VFX).
At the Fake Merchant, throwing it reveals the impostor and triggers a boss fight against the Fake Merchant Monster (165-175 HP). Beat it to earn The Merchant's Rug??? relic and all unpurchased fake relics.
