Three Pearlspore Bells are in the basement of The Blushing Mermaid. These fungi, pulsating with healing energy, are the secret to Auntie Ethel's supernatural regeneration. As long as one or more survive, a dead Auntie Ethel is resurrected at the start of the next turn with Fungal Resurrection.
Destroying all three mushrooms allows the party to finally put an end to the hag's life. This can be achieved before the fight begins by going straight to her lair without confronting Ethel disguised as Captain Grisly, placing a sufficient quantity of explosives near each bell, and triggering them simultaneously using a spell like Magic Missile or Scorching Ray.
