MMCO

MMCO — full RPG layer for Minecraft 1.21.1 (Fabric)
An MMORPG layer where the players build the civilizations and the commerce: 23 classes sharing a 704-node talent tree, 15 professions with their own quests and minigames, a world of its own — 88 custom biomes across the Overworld, Nether and End, laid out in danger tiers T0–T10 — 12 bosses, 1,000+ weapon variants, custom forge & enchanting, trinkets, guilds with missions and diplomacy, claims, a fully player-driven economy and a Phone hub (press ESC) that ties it all together.
⚠ Heads-up: this mod is built for the MMCO server.
It runs standalone, but many systems — the talent tree, class balance, professions, quests, biome tiers, mob tiers/variants, boss spawns, shop prices — are driven by server-side configuration files. Installing just the mod gives you the built-in defaults, which are generic and out of date compared to the live server.
👉 For the complete, tuned experience, install the official modpack instead: search for MMCO RPG on CurseForge (or find it under my projects). The pack ships the mod plus the combat/performance/multiplayer mods and pre-set configs, with the server already in your list — one click and you’re in.
What’s in the mod

• Classes — 23 of them, from Warrior, Mage and Healer to Reaper, Ninja, Druid and Artificer; active skills on their own hotbar, a second class late in the game
• Professions — 15 jobs (Miner, Farmer, Smither, Cooker, Enchanter, Merchant, Tamer…) with quests, talents and reward tracks
• World — custom biomes in every dimension, tiered by distance from spawn: the further you go, the stronger the mobs and the better the materials; scaled mob variants and custom structures along the way
• Gear — weapons and armor forged by material, reagent and wood; custom enchantments; trinkets
• Community — guilds (titles, missions, buffs, diplomacy), claims, player shops, market and direct trade
