Cobblemon Nuzlocke Mode
by Raguto
Cobblemon Nuzlocke Mode is a Cobblemon challenge add-on that enforces Nuzlocke rules, such as losing fainted Pokémon and limiting catches per biome.
What it does
Players who follow the Nuzlocke ruleset can enable it on a world. Fainted Pokémon are released automatically, Pokémon Center healing is turned off, and each biome allows only one catch and one spawn per biome instance. A species already owned cannot be caught again, and a catch cooldown can be set as an optional timer of 0 to 60 minutes between catches.
The mod requires Cobblemon and Fabric API on Fabric. On NeoForge it also needs Cobblemon, and it runs on client and server, so the server and every player need it. Files are published for Fabric and NeoForge, with 1.2.4 for 1.21.1 as the latest file, under All rights reserved, so the code is not open source.
Key features
Nuzlocke challenge rules
Adds a set of Nuzlocke rules that apply to Cobblemon runs, including the biome and species limits.
Shiny clause
Shiny Pokémon remain catchable regardless of the other rules, so the clause never blocks them.
Adjustable combination rules
Individual rules can be toggled to build a custom challenge rather than a single fixed ruleset.
Per-player settings
Settings are stored for each player and persist across sessions, and the run is configured on first join.

How it compares
Cobblemon Shiny Days is a server-side only option, open source under the MIT License, with files for 1.21.1. Pokemon Fair Catch runs on client and server, is open source under the MIT License and also targets 1.21.1. Cobblemon Nuzlocke Mode differs by enforcing the Nuzlocke rule set itself, and it is not open source.
