Fathoms
by LeadisToxic
Fathoms adds fishing content to Minecraft through a datapack, with more than 70 fish, a rebuilt loot table and a dredging system for deep waters.
What it does
The datapack overhauls the fishing loot table and adds a new bait system, so catches depend on where and how a player fishes. Two new mini-biomes carry their own mechanics and fish. Two interactive blocks let players automate and diversify fishing, and a ritual system works away from water. Dredging provides metal farming and uncovers ancient secrets, and a collection of trinkets and novelty items can be found at sea.
The pack suits survival worlds where fishing is a long-term activity, and it fits alongside other fishing mods and datapacks. Its author notes that some datapacks make small changes to fishing loot tables, so load order can matter when several packs touch the same tables. Fathoms is released for Fabric, Forge, NeoForge and Quilt as a data pack and works with game versions 1.21.5 – 1.21.10, with a server required and clients optional. The code is not open source and is covered by All rights reserved.
Key features
More than 70 fish
A large set of fish is spread across varied biomes and conditions, so each sea area can yield different catches.
Rebuilt loot table
The fishing loot table is reworked and paired with a new bait system that changes what a rod can bring up.
Two mini-biomes
Two added mini-biomes each hold exclusive mechanics and fish that do not appear elsewhere.
Dredging and ritual systems
Dredging yields metal and ancient secrets, while a cryptic ritual system provides power away from the water.
