Fishing Mechanics & Bait

The mod enhances the vanilla fishing experience by introducing specific baits that increase the weight of certain fish in the loot table.

Bait Types

Earthworms: Used to catch Plentifins, Wildsplashes, and Wreckers. Found by digging Grass or Dirt.
Grubs: Used to catch Devilfish and Battlegills. Found by digging Sand.
Leeches: Used to catch Ancientscales and Stormfish. Found by digging near shorelines.

How to Use Bait

To use bait, hold the bait item in your off-hand while casting your Fishing Rod. The bait will be consumed upon a successful catch. Using the correct bait increases the Lure speed by 10% and significantly boosts the chance of catching the associated fish species.

Fish Shoals

Shoals are a new entity that appears in Rivers, Beaches, and Oceans. They contain a group of fish that can be caught more easily. Removing water or placing solid blocks in a shoal will cause it to disappear.

Advancements

The mod adds over 50 advancements to track your fishing progress: * Hunter of [Fish Type]: Catch all 5 variants of a specific species. * Legendary Hunter of the Sea of Thieves: Catch every single fish variant in the mod. * Shoal Hunter: Catch a fish from a naturally spawning shoal. * Drunken Sailor: Catch a Rum Battlegill while under the Nausea effect. * Hidden Advancements: Awarded for rare interactions, such as catching a Shadow Stormfish during a peak storm.
