Pasture Blocks

Cobbleverse uses the Cobbreeding mod. Pokémon compatible for breeding must be placed inside Pasture Blocks. By default, they have a 50% chance every 10 minutes to produce an egg, but in Cobbleverse this interval is 6 minutes.

Pasture block setup

Behind angle showing eggs

Eggs appear behind the pasture block. Right-click the bottom of the block to collect them. Pasture blocks can also connect to storage blocks via hoppers, making an automated egg farm possible.

Each interval, the pasture block looks for two compatible parents. For best results, use one pasture per breeding pair — otherwise, parents are chosen randomly if more than two are inside.

IV Inheritance

Without any held items, offspring inherit 3 random IVs from the 12 total IVs of both parents. The rest are randomized.

• Power Bands: Lock a specific IV from the parent holding it. (Ex: Def Power Band guarantees DEF IV.)
• Destiny Knot: Ensures 5 out of 12 IVs are inherited.
• Only one IV will always remain random.

⚠️ Don’t give both parents Power Bands — only one is chosen (50/50).

Strategy: use Power Bands if your Pokémon has only 1 IV. Switch to Destiny Knot once it reaches 2 IVs or more. You can also combine a Destiny Knot + one Power Band to guarantee one stat while passing others.

Practical Breeding Example

Start with an Eevee with 3 perfect IVs. Give one parent a Destiny Knot and connect your Pasture Block to a hopper/chest. Eggs will collect in the chest:

• Discard eggs with 2 IVs or less.
• Hatch 3+ IV eggs and recycle them into the pool.
• Repeat until you reach 5 IVs, then 6 IVs.

Power Bands are only useful early when parents have low/no IVs.

Shiny Breeding

Default Cobblemon shiny rate: 1/8196. In Cobbleverse: 1/2048.

Breeding multiplies these odds. In Cobbleverse, shiny chance is 16× by default:

• Always: Every breed = 16/2048 chance.
• Masuda Method: Parents from different original trainers.
  (⚠️ Not enabled by default — add "masuda" to shinyMethod in config/cobbreeding/main.json.)
• Crystal Method: Shiny parent(s) increase the odds further.
  (⚠️ Not enabled by default — add "crystal" to shinyMethod in config/cobbreeding/main.json.)

Masuda + Shiny parents + Always = near-guaranteed shiny odds with the right setup.

Hidden Abilities

Only female Pokémon pass down Hidden Abilities (HAs), and only by chance:

• 3 regular abilities → 10% chance
• 2 regular abilities → 20% chance
• Female with HA → 60% chance

Items like Ability Patch or Ability Capsule can set abilities directly.

Natures

Natures affect stat growth. Example:

• Jolly: +Speed, –SpA
• Timid: +Speed, –Atk

To lock a nature: give the parent an Everstone.

Overall Setup

• One parent holds Destiny Knot.
• The other holds Everstone (if you want its nature passed down).
• Hidden Abilities are RNG — use Ability Patch if unlucky.

Optimal breeding setup: Destiny Knot + Everstone

🥚 Egg Hatching Pro Tip

You will receive the Pokémon Egg as an item. It will hatch over time if kept in your inventory. You can speed up this process by having a Pokémon with the ability Flame Body, Magma Armor, or Steam Engine in your party. This halves the hatching time by taking 2 seconds off instead of 1. (The effect does not stack.)

⚙️ Config & Pro Tips

The config file is located at: installation folder > config > cobbreeding > main.json

• "eggCheckTicks": Lower this to reduce time between egg checks.
• "eggCheckChance": Set to 1.0 to guarantee an egg each check (default 0.5 = 50/50).
• "eggHatchMultiplier": Set to 0.0 for instant hatching, or lower than 1.0 to reduce hatch time. (Does not affect eggs already generated before the change.)

Optimized config: 10s egg checks, 100% egg chance, instant hatching
