Cobblemon Raid Dens Addon - Auto Raid Den Designs

The addon assigns Cobblemon Raid Dens arenas by a raid boss's primary element type instead of by its name. Each type maps to one arena: Fire, Water, Electric and Ice each get their own, Grass and Bug share a Fairy grass arena, Rock, Ground and Fighting share a fighting arena, and Dark, Ghost and Psychic share a dark arena. Name-based JSON lists are replaced by this type lookup, so a boss added by another mod is assigned an arena on its first spawn.

Without the addon, the base mod can place bosses in custom dens, yet each boss must be listed by hand in a JSON file before it spawns in the matching design. Keeping that list current becomes harder as the roster grows. This addon checks the boss's primary type and picks the correct arena automatically.

The addon is server-side only, so players join without installing it. It requires Cobblemon Raid Dens Addon - Raid Den Designs and the custom den arena structures supplied through the DesignerRaid Required Server Worlds Datapack. It is published for Fabric and NeoForge for 1.21.1, and the code is not open source; it is released under All rights reserved.
