Cobblemon Expeditions

Send your Pokémon on timed expeditions to earn loot, XP, and climb the ranks!

Cobblemon Expeditions is a Fabric mod for Minecraft 1.21.1 that adds an expedition system to Cobblemon. Players interact with tiered Expedition Boards to dispatch their PC Pokémon on timed missions. Choose your team wisely — type matchups, IVs, EVs, and environmental hazards all influence your chances of success.

Required on both client and server.

⚔️ Features

Core Gameplay

• 5 Board Tiers — Copper, Iron, Gold, Diamond, and Netherite. Higher tiers unlock harder expeditions, passive bonuses, and more modes.
• 11 Expeditions — 8 standard expeditions (Forest Forage, Shoreline Survey, Cave Delve, Berry Grove Harvest, Volcanic Survey, Deep Sea Dive, Frozen Ruins, Distortion Rift) plus 3 boss encounters.
• TEP System — Team Expedition Power is calculated from type advantages, IVs, EVs, party size, hazard mitigation, and augment bonuses.
• 4 Outcome Tiers — Expeditions resolve as GREAT, SUCCESS, PARTIAL, or FAIL — each with different loot quantities and quality.
• Pokémon & Player XP — Pokémon gain experience and players earn vanilla XP upon claiming rewards.

Board Upgrades

• In-Place Upgrades — Upgrade your board from Copper to Netherite using block materials without breaking it. The entire 3×2 multiblock transforms in place.
• Tier Bonuses — Each upgrade grants passive bonuses: extra expedition slots, faster expeditions, better loot, higher great success chances, improved hazard mitigation, and newly unlocked modes.
• Progression Path — Copper → Iron (8 Iron Blocks) → Gold (8 Gold Blocks) → Diamond (8 Diamond Blocks) → Netherite (8 Netherite Blocks).

Boss Expeditions

• 3 Boss Encounters — Legendary Sighting, Titan’s Den, and Ultra Wormhole. High-risk, high-reward endgame challenges requiring massive team power.
• Entry Costs — Boss expeditions consume items to start (default: Enchanted Golden Apple). Configurable per expedition.
• Weekly Cooldowns — Boss expeditions have a 1-week cooldown between attempts.
• Exclusive Loot — Master Balls, Ability Patches, Choice items, Life Orbs, Focus Sashes, mints, Nether Stars, and more.

Fatigue System

• Pokémon Fatigue — Pokémon gain fatigue after each expedition, reducing their TEP contribution by 10% per level.
• Exhaustion — At max fatigue (5 levels), Pokémon are exhausted and cannot be sent on expeditions until they rest.
• Natural Recovery — Fatigue recovers at 1 level per hour. Boss expeditions cause double fatigue.
• Anti-Spam — Prevents sending the same Pokémon endlessly, encouraging roster diversity.

Augments

• 5 Purchasable Augments — Buy augments with vanilla items, then toggle them on or off freely. Stack multiple for custom strategies.
  • 🪶 Swift Feather (16 Feathers) — Expeditions 15% faster
  • 🍀 Lucky Charm (4 Rabbit Feet) — +15% loot quality, +10% loot quantity
  • 💎 Power Crystal (16 Amethyst Shards) — +5 TEP per Pokémon, +5% success chance
  • 🔔 Soothing Bell (1 Bell) — Reduces fatigue gain by 1 per expedition
  • 🔍 Scholar’s Lens (1 Spyglass) — +25% rank XP earned
• Data-Driven — Server admins can create custom augments with any item cost and effect combination.

Expedition Modes

• 8 Modes — Each mode alters expedition rules with meaningful tradeoffs. Change freely between expeditions.
  • ⚡ Rapid Deployment — 15% faster, but -10% loot
  • 🔎 Deep Scavenging — +15% loot, but 15% slower
  • 🛡️ Safe Operations — 50% hazard reduction, slightly lower great chance
  • 🎯 Specialist Contracting — +12% type bonus (cap 36%), -5% on non-matching Pokémon
  • 📦 Bulk Logistics — +1 expedition slot, -12% loot quality
  • 🏺 Relic Hunters — +20% rare loot, but 20% slower and success capped at 90%
  • 📚 Training Detail — +75% Pokémon XP, -15% loot
  • 💊 Field Medicine — 10% hazard reduction, -5% loot
• Tier-Gated — Modes unlock progressively as you upgrade your board, creating a meaningful progression loop.

Hazards

• 7 Hazard Types — Heat, Cold, Toxic, Cave-in, Aquatic, Electric, and Dark.
• Type Mitigation — Each hazard is countered by specific Pokémon types. Unmitigated hazards reduce your TEP score.
• Data-Driven — Custom hazards can be defined with custom type resistances and penalty values.

Rank Progression

• Expedition Rank XP — Earn XP to level up your expedition rank. Higher ranks unlock new board tiers and harder content.
• Additional Slots — Higher ranks grant more concurrent expedition slots.

Quality of Life

• Sound Effects — Rich audio feedback for starting expeditions, claiming rewards, upgrading boards, buying augments, errors, and more.
• 3×2 Multiblock Boards — Beautiful 3-wide, 2-tall craftable blocks with tier-appropriate textures. Diamond and Netherite boards feature animated screen effects.
• Search & Filter — Filter expeditions by type, search Pokémon by name, and auto-select the best team.
• Crafting Recipes — All 5 board tiers are craftable with tier-appropriate materials.

Customization

• Fully Data-Driven — All expeditions, loot tables, modes, hazards, and augments are defined via JSON datapacks and editable in-game.
• In-Game Admin Editor — Operators can create, edit, and delete expeditions, loot tables, modes, hazards, and augments live — no restart required.
• Highly Configurable — Dozens of config options for TEP calculation, success thresholds, loot scaling, rank progression, fatigue rates, boss cooldowns, anti-abuse, and more.
