Cobblemon Randomizer

Cobblemon Randomizer is an addon for Cobblemon that adds a randomized Nuzlocke-style challenge system to your Cobblemon playthrough.

Start with randomized starter choices, then use Challenge Tokens to unlock legal target Pokémon from different biomes. Track your run with the Challenge Journal, follow stricter catch rules, and manage fallen Pokémon through built-in Nuzlocke death mechanics.

Recommended Companion Mods

Cobblemon Randomizer does not add trainers, trainer battles, NPC opponents, gyms, quests, or structured battle encounters.

For a fuller Nuzlocke-style experience, it is recommended to play alongside other Cobblemon-compatible mods that add trainers, NPC battles, or additional battle content.

Cobblemon Randomizer focuses on:

• randomized starters
• biome target unlocks
• catch restrictions
• Challenge Tokens
• Challenge Journal tracking
• Nuzlocke death rules
• Hardcore run-fail support

Trainer progression and NPC battle content are outside the current release scope, but are planned for implementation once it comes to Cobblemon.

How It Works

When you begin your Cobblemon journey, the normal starter list is replaced with randomized starter options. These 3 options can be from any region.

After choosing a starter, your Nuzlocke begins, and you receive a Challenge Journal.

To catch more Pokémon, craft or obtain Challenge Tokens. Right-click a token while standing in a biome to unlock that biome’s target Pokémon.

The biome determines the target, but the target can be caught anywhere as long as it is caught during battle.

---

Challenge Journal

The Challenge Journal tracks your run in-game.

It includes:

• Available Targets
• Locked Until Tomorrow
• Failed Challenges
• Completed Challenges
• Fallen Pokémon
• Run Status
• Rules and token instructions

---

Nuzlocke Rules

Only Pokémon listed as available targets may be caught.

Target Pokémon must be caught during battle. Direct overworld catching is blocked.

If a target Pokémon faints or you flee from its battle, the target fails. Depending on config, failed targets either become available again the next Minecraft day or fail permanently.

When one of your Pokémon faints in battle, it becomes Nuzlocke-dead. Dead Pokémon remain in your party or PC, but they stay at 0 HP and cannot be healed back into usability.

If you have no usable Pokémon remaining in your party or PC, the run fails.

---

Hardcore Support

In Hardcore worlds, failing the Nuzlocke triggers Minecraft’s normal Hardcore death.

It is recommended that you enable permanent challenge losses if you fail to catch or flee from a challenge Pokémon, but this is disabled by default in the config.
