Demon Conch

The Demon Conch is an item obtainable from fishing in lava. When used, it teleports the player to the center of the Underworld.

Like the Magic Mirror, it can be used an indefinite number of times. This makes it a viable alternative to a conventional Hellevator.

Trivia

 * It has the slowest use time in the game, tied with the Magic Mirror, Magic Conch, and Snake Charmer's Flute.
