Tidemark Additions

by jackydoge

Tidemark Additions adds two aquatic mobs, armor, tools and items to Forge, drawn from ocean and deep ocean biomes and the loot of its mobs.

ForgeClient and serverMIT LicenseOpen source1.21.1

What it does

The mod spawns in ocean and deep ocean biomes, where its two new mobs appear. Tidescales and abyssal hides drop from them, and those drops are used to craft Tidesteel and Tidemarked gear. Driftsteel fragments can be found in shipwrecks and underwater ruins, and driftsteel is crafted from them. Tidesteel ingots combine tidescales with driftsteel, and tidemarked ingots combine abyssal hides, driftsteel, tidescales and resonant scales. Resonant scales come from the Warden's loot.

The mod gives the Forge player a set of new gear materials and a progression that moves from ocean mobs to deeper loot. Wearing every piece of the Tidesteel set activates the Undertide effect. Tidemark Additions is open source under the MIT License and needs Geckolib on Forge for 1.21.1; Just Enough Items (JEI) is optional. A server running it needs every connecting player to have it too. The latest Forge file is 1.0.0 for 1.21.1, published 2025-11-29.
