Radical Cobblemon Trainers
by hd42
With Radical Cobblemon Trainers installed, a world gains over 1500 trainers taken from the Radical Red and Unbound ROM hacks and from Brilliant Diamond and Shining Pearl, and they spawn naturally.
What it does
The trainers come from Radical Red (v3.02), Unbound (v2.0.3.2) and the main series games Brilliant Diamond and Shining Pearl. Trainers appear in different biomes, and a story mode runs through leaders, rivals and other key figures. Players reach the path through the Trainer Association, where they choose a route of their own.
Player progression is capped by level. Pokemon in the party stop gaining experience below the current cap until the next key trainer, such as a gym leader, is defeated. A Trainer Card tracks progress, lists trainer information and shows where the next key trainer is once it spawns nearby. The endgame keeps challenging trainers available after the champion title, with stronger trainers giving better loot.
The mod requires Cobblemon, CobblemonTrainers (Discontinued), Forge Config API Port and Radical Cobblemon Trainers API. Radical Cobblemon Trainers is published for Fabric, Forge and NeoForge for 1.20.1 and 1.21.1, and it runs on client and server, so the server and every player need it. The license is custom and the mod is not open source.
