A Poção Nefasta tem 3 usos

O item mais dependente de contexto do jogo — dano em combate, ouro do mercador e gatilho do chefe Falso Mercador.

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.
