Cobble Combo

This mod for Cobblemon replicates the catch combo system from the Let's Go! series. It rewards you for catching the same species back-to-back. Chain consecutive captures of one species to build a combo, and the higher it climbs, the better your rewards get. Catching a different species breaks the chain and starts a new combo at 1.

How it works

Just like the catch combos introduced in "Let's Go Pikachu/Eevee":

• Capturing a Pokémon of the same species as your current chain increases your combo count by 1.
• Capturing a different species breaks the current chain and starts a new combo at 1 for the new species.
• Your combo and the resulting shiny odds are shown in chat and/or the action bar as you catch.
• Combos persist per-player across server restarts.

Since Cobblemon is so vast in comparison to the main game, the combo benefits expand past the 41+ chain length.

Catch rate multiplier

Applied directly to the Poké Ball's catch rate for the species you're chaining, making the next capture easier. Thresholds and multipliers are configurable via catchRateTiers — see Configuration.

Shiny odds

Base odds start at 1/8192 and halve every stepSize catches (10 by default), down to a floor of 1/512. Both values are configurable — see Configuration.

Guaranteed perfect IVs

Once your combo is high enough, captures are guaranteed a number of perfect (31) IVs, randomly distributed across HP, Attack, Defence, Special Attack, Special Defence, and Speed. Thresholds and IV counts are configurable via perfectIvTiers — see Configuration.

Hidden ability chance

On capture, there's a chance the Pokémon's ability is rerolled into its hidden ability, if it has one. Thresholds and chances are configurable via hiddenAbilityTiers — see Configuration.

Spawn bias

While chaining, nearby wild spawns have a chance to be converted into the species you're chasing, making it easier to keep the combo alive. Requires enableSpawnBias to be true. Thresholds and chances are configurable via spawnBiasTiers — see Configuration.

Configuration

Settings live in config/cobblecombo.json, generated on first run:

Each tier list is scanned for the highest combo threshold you've reached, and its value is applied — you don't need one entry per combo count, only the breakpoints where the bonus changes. Tiers can be added, removed, or reordered freely; if a list is left empty or removed, that bonus is effectively disabled (catch rate falls back to 1.0x, everything else to 0).

Example: customizing each tier setting

Each value means something different depending on the table it's in — a multiplier, a raw IV count, or a 0.0–1.0 chance. Here's a custom curve for each, all steeper than the defaults:

catchRateTiers — value is a multiplier applied to the Poké Ball's catch rate:

"catchRateTiers": [
  { "combo": 3,  "value": 1.25 },
  { "combo": 10, "value": 2.0 },
  { "combo": 25, "value": 4.0 }
]

perfectIvTiers — value is the number of guaranteed perfect IVs (whole numbers, capped at 6):

"perfectIvTiers": [
  { "combo": 10, "value": 2 },
  { "combo": 50, "value": 4 },
  { "combo": 150, "value": 6 }
]

hiddenAbilityTiers — value is a chance from 0.0 (0%) to 1.0 (100%):

"hiddenAbilityTiers": [
  { "combo": 50,  "value": 0.10 },
  { "combo": 150, "value": 0.25 },
  { "combo": 250, "value": 0.50 },
  { "combo": 400, "value": 1.00 }
]

spawnBiasTiers — also a 0.0–1.0 chance, and only applies while enableSpawnBias is true:

"spawnBiasTiers": [
  { "combo": 25,  "value": 0.15 },
  { "combo": 75,  "value": 0.40 },
  { "combo": 200, "value": 0.70 },
  { "combo": 500, "value": 1.00 }
]

Every table is scanned the same way: whichever entry has the highest combo you've reached is the one that applies. In the hiddenAbilityTiers example above, combos below 50 get 0% (no matching tier), 50–149 get 10%, 150–249 get 25%, 250–399 get 50%, and 400+ is guaranteed.

Reload the config in-game without restarting via /cobblecombo reload — this re-reads the entire file, including all tier lists, and applies immediately to future catches, spawns, and captures.

Commands

/cobblecombo bar and /cobblecombo chat are per-player preferences — anyone can run them to opt out of their own action bar/chat notifications without affecting other players. set, toggle chat/bar/spawnbias, and reload are server-side and require op, since they change behavior for everyone or the whole config.

Notes

• If using the catch rate display mod, Catch Rate Display, the catch rate for a catch combo will not be reflected!
