CobbleCatalyst adds Cobblemon trainer battle phases to Cataclysm boss fights.
When a boss reaches its configured health threshold the boss becomes invulnerable and frozen. Players must defeat a Cobblemon trainer challenge to resume the fight. If they lose, forfeit, disconnect, or ignore the challenger for too long, the boss resets and nearby participants are punished. If there is more than one player fighting the boss then mobs will spawn in the arena while fighting the trainer, giving the second player the objective of defending the other player fighting the trainer.
This mod currently supports Cataclysm bosses with datapack-configured trainer teams, level scaling, support mob pressure, and multiplayer scaling.
