Moon Shell

The Moon Shell is a Hardmode accessory that can be crafted at the Tinkerer's Workshop. It combines the effects of the Moon Charm and the Neptune's Shell: Equipping it will turn the player into a Merfolk when entering water (at any time), or into a Werewolf at night. The Merfolk form replaces the Werewolf form if entering water at night.

The buffs from the Moon Charm:

The buff from the Neptune's Shell:
 * The player will be able to move freely in water.

Tips

 * While the components of the Moon Shell sell for a combined, the Moon Shell only sells for (23.81% less).
 * The Moon Charm is rarer than Neptune's Shell despite having the same drop rate due to werewolves spawning in much lower numbers during a full moon than creatures of the deeps do during an eclipse. A Blood Moon will increase the Werewolf spawn rate. A naturally occurring full Blood Moon occurs an average of once in 72 days, during which time 3–4 eclipses can be expected even without.

Trivia

 * The Moon Shell resembles a purple Neptune's Shell carved into an angled Moon Charm.
