Cobblemon Realms — Biome Expanded Spawns v5.0b

Spawn Fix Patch & Legendary Nerf Pass

🛠️ Spawn Fixes

Several Pokémon had spawn entries that were:

  • incorrectly enabled
  • missing activation flags
  • or using conditions that prevented them from spawning as intended

v5.0b corrects all these issues. The affected species now spawn properly with the right biome tags, contexts and conditions.


🔻 Global Legendary & Ultra Beast Nerf

Legendary, Mythical and Ultra Beast spawn rates were far too high in v5.0.

v5.0b applies a full rarity pass:

  • significantly reduced weights
  • corrected bucket tiers
  • stricter biome routing
  • cleaned level ranges
  • lowered overall spawn frequency across the board

This restores legendary rarity to a realistic and balanced level, in line with CR gameplay expectations.


🎯 Goal of the Patch

This update focuses on:

  • stabilizing 5.0’s big overhaul
  • ensuring every Pokémon that should spawn actually does
  • correcting overpowered legendary/UB presence
  • preparing the ground for future balancing waves

📌 Compatibility

v5.0b works only with Cobblemon 1.7+ (Minecraft 1.21+).
