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 "anonymously" rarer than the Neptune's Shell. On the one hand, the Charm's drop rate is almost as high and full moons are more common than Solar Eclipses; on the other, even a single Solar Eclipse will spawn many Creatures From the Deep, while Werewolves are limited to normal spawn rates and the shorter length of the night versus day. A Blood Moon will increase the Werewolf spawn rate, but a 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.
