Cobblemon Realms — Biome Expanded Spawns v5.0

Major Overhaul From v4.9 → v5.0

⚠️ Compatibility Notice

v5.0 only works with Cobblemon 1.7+. It will not run on Cobblemon 1.6.

🧬 What Actually Changed in the Spawns

v5.0 is not a cosmetic update. It is a full ecosystem overhaul built around the new Cobblemon 1.7 spawn architecture.

Below is the detailed, transparent breakdown of what changed.

---

🌍 1. Full migration to Cobblemon 1.7’s new biome and condition system

Cobblemon 1.7 reworks the entire spawn backend:

• new biome tag structure
• new condition rules (canSeeSky, underground, water logic…)
• new spawn contexts (surface, grounded, subterranean…)
• updated routing for climate groups and biome families

Every Pokémon file in the datapack has been rewritten to comply with these rules.

Examples included in v5.0:

• Migration to the new #cobblemon:* biome tags
• Replaced outdated logic that no longer exists in 1.7
• Updated mountain, temperate, cave and other biome families
• Clean separation between surface, underground and in-water behaviors

This ensures the datapack is fully aligned with Cobblemon’s new spawn engine.

---

📁 2. Over 100 duplicate Pokémon files merged

A massive cleanup was done to remove conflicts between:

• non-numbered files (victreebel.json)
• and their official numbered counterparts (0071_victreebel.json)

In v5.0, all “real” Pokémon spawn data has been merged into their correct Pokédex file.

Examples:

• Victreebel
• Seviper
• Dialga
• Many more (literally over a hundred)

Result: No more duplicates, no more conflicting rules, proper structure for every Pokémon.

Fakemons and custom Realms-exclusive forms were not touched.

🐾 3. Large-scale spawn distribution rebalance

Many species were previously too exclusive, locked into extremely narrow biomes or micro-conditions.

v5.0 expands their distribution to match Cobblemon 1.7’s broader, tag-driven environments.

What that means in practice:

• Several Pokémon now spawn across multiple valid biome groups instead of a single one
• Restrictions based on outdated biome lists were removed or modernized
• The spawn buckets were refined so some species are no longer artificially rare or artificially common

This is the first step of a long-term rebalance. Future versions will continue expanding, correcting or specializing various species as Cobblemon evolves.

---

🧱 4. Structural rewrites inside spawn pools

This update includes dozens of structural improvements:

• cleaned weight distributions
• fixed incorrect level ranges
• normalized spawn contexts
• aligned bucket logic with Cobblemon 1.7 behavior
• removed leftover obsolete conditions from pre-1.7 versions

The goal is a more predictable, more stable and more readable spawn ecosystem.

---

🌀 5. New Dimension Support (Where Applicable)

v5.0 updates several spawns to correctly work with:

• modern Nether biome tags
• updated End dimension logic
• revamped overworld climate grouping

Some species that were previously “exclusive” due to outdated dimension constraints are now correctly detected and mapped.

---

🔧 6. Preparing for future balancing waves

This update lays the groundwork for future improvements. As a result:

• some Pokémon now have broader biome coverage
• others will be re-specialized later
• certain families will receive deeper reworks in upcoming versions

The spawn system is now flexible enough to allow much more fine-tuned balancing moving forward.
