Mystic Seas
by CrowFaced
Mystic Seas, a Forge mod for 1.20.1 by CrowFaced, adds mermaids with tails and some siren-related abilities to the game.
What it does
Mermaids are the central element. Players can trade Prismarine Crystals with different mermaids to obtain scales, which are then used to craft a Neptune's trident. Trading more crystals with the mermaids makes scales available that customize the color of a tail through a Smithing Table with Prismarine Shards.
The mod also lets a player become a mermaid through the favor of the mermaids. Stealing hearts is another path: a String of Broken Hearts can be crafted and traded to the Sea Witch, who alters the look of a player's own scales. The mod began as part of the Sacred Grove Mod, where its mermaids were first shared, and was later ported to 1.20.1 as a separate mod.
Mystic Seas runs on Forge only, with a single game version, 1.20.1, and its latest file is 1.1.0 for 1.20.1, published on 2025-05-16. It is released under All rights reserved and is not open source. Installation needs Curios API, Geckolib and Kleider's Custom Renderer API. The server and every player need the mod installed.
