Merfolk

Merfolk is a buff granted to the player who equips the Neptune's Shell or the Moon Shell underwater. It grants the player the ability to breathe underwater, entirely removing the Breath meter. Also, the player is given the ability to swim similar to that of equipping the Flipper. The player moves through water as though it was open air with no reduction in speed. They can also hold space to swim upward, and sink automatically. However, if under a Water Walking effect, players will have to hold the down key (default 's') to descend.
