[Cobblemon] TrainerAttributesLib
[Cobblemon] TrainerAttributesLib connects Minecraft's attribute system to Cobblemon, so attribute values can change Pokémon outcomes such as catch rates and experience.
What it does
The library reads Minecraft attributes and applies them to Cobblemon mechanics. Each attribute can raise a chance or a stat: experience gained from a battle, the catch chance, the shiny chance, the hidden ability chance, the critical catch chance and the spawn chance. Several types of boost are available for each one, and bonus IVs can be tied to specific stats.
The mod is built mostly for use with Accessories through Curios, though the attributes can also come from armor pieces. Because it is a library, it adds no items or blocks of its own; it changes behavior when another mod or a datapack supplies attribute values. It is a Fabric mod for Minecraft 1.21.1 and runs on client and server, so both the server and every player need it. It is released under All rights reserved, so it is not open source.
[Cobblemon] Trainer Accessories requires this library, so installing that mod alone is not enough. The library is published for Fabric only, with the latest file 1.7.2-1.0.2 for 1.21.1, released 2026-07-18.
