Mod made at request for Majestic

The FishingBonus mod enhances the fishing experience in the game by allowing players and modders to customize the drops obtained from fishing. With this mod, each type of fish can have its own unique set of items that it can drop when caught. These settings are easily configured through a YAML file, giving users the flexibility to:

  • Add or replace default drops: Decide whether new item drops should be added to the existing default drops of a fish or completely replace them.
  • Control drop quantities: Specify the minimum and maximum number of items a fish can drop.
  • Adjust drop chances: Set the probability for drops to occur, offering the ability to fine-tune how often items are received from fishing.
  • Ensure variety with one of each: Choose whether a fish can drop one of each item listed or if duplicates of the same item can appear in a single catch.
  • Weight items differently: Influence the likelihood of each item being dropped through relative weight settings, allowing for rare or common drops.

This mod opens up new possibilities for game customization and enrichment, making fishing a more rewarding and exciting activity tailored to the player's or modder's preference.

Version checks with itself. If installed on the server, it will kick clients who do not have it installed.

This mod uses ServerSync, if installed on the server and all clients, it will sync all configs to client

This mod uses a file watcher. If the configuration file is not changed with BepInEx Configuration manager, but changed in the file directly on the server, upon file save, it will sync the changes to all clients.

Installation Instructions

You must have BepInEx installed correctly! I can not stress this enough.

Fish Drops Configuration Guide

This guide explains how to customize fish drops in the game using the YAML configuration file provided by the FishingBonus mod. This feature allows you to tailor the loot that each fish drops upon being caught, including the chance of dropping, the minimum and maximum number of items dropped, and whether to add these drops to the default ones.

YAML Structure

Below is the general structure of the YAML configuration file for defining fish drops:

Please note: This is an example and not the actual file. The actual file will be generated upon first run of the mod by the time you are at the main menu. All fish found in your game will be added to the file automatically.

The file will be located at BepInEx/config/Azumatt.FishingBonus.yml once generated. If you do not see the file, you can create it manually, the current vanilla generated file will look like the one on my github page here: FishingBonus Example Config

    addToDefaultDrops: false
    dropMin: 1
    dropMax: 1
    dropChance: 1.0
    oneOfEach: false
      - item: Stone
        minStack: 1
        maxStack: 2
        relativeWeight: 1.0
      - item: Amber
        minStack: 1
        maxStack: 1
        relativeWeight: 0.9


  • addToDefaultDrops: If true, custom drops are added to the fish's default drops. If false, the custom drops replace the default ones.
  • dropMin: The minimum number of different items the fish will drop.
  • dropMax: The maximum number of different items the fish will drop.
  • dropChance: The chance (0 to 1) that any drops will occur at all.
  • oneOfEach: If true, ensures that only one of each item in the drops list will be dropped. If false, multiple items of the same type can be dropped based on their relativeWeight.
  • drops: A list of items that the fish can drop, each with its own configuration:
    • item: The name of the item prefab to drop. This must match the item's internal name in the game.
    • minStack: The minimum stack size for the item when it drops.
    • maxStack: The maximum stack size for the item when it drops.
    • relativeWeight: Influences the likelihood of this item being dropped relative to other items in the list. Higher values increase the chance.

Adding Custom Fish Drops

  1. Identify the Fish: Determine the internal name of the fish for which you want to customize drops. This name must exactly match the fish's name as defined in the game.

  2. Configure Drops: Follow the structure shown above to add or modify the fish's drops. You can specify as many items as you wish under the drops section for each fish.

  3. Adjust Drop Behavior: Use the addToDefaultDrops, dropMin, dropMax, dropChance, and oneOfEach parameters to control how and when drops are added.

  4. Save Changes: After configuring your fish drops, save the YAML file and ensure it's correctly placed in the mod's configuration directory.

  5. Reload/Restart: Depending on the mod's capabilities, you may need to reload the configuration or restart the game for changes to take effect.


To ensure a fish named Fish1 always drops between 1 to 2 stones with a high chance, alongside 1 amber with a slightly lower chance, and these are the only drops (replacing any default drops), your YAML configuration would look like the example provided above.
