Arenas_LD

Arenas_LD arranges mob spawners into battles. A trigger activates the encounter once a player enters a configurable radius, and the battle is won only when the spawned mobs are defeated. When players leave the battle area, the arena resets. Spawner settings include the mob ID, mob count, spread, respawn cooldown, and a group ID that links several spawners so they can control phase blocks and team mobs together.

Each mob's attributes and equipment are set on dedicated screens: max health, attack damage, armor for head, chest, legs and feet, plus the main and offhand items and their drop chances. The mod also has a boss spawner for single bosses and raid mechanics for larger encounters. A required player count can be set, and the server broadcasts a server-wide message when the encounter starts.

The mod is built for map makers who want to control mob spawning and battle progression. A server running it needs every connecting player to have it too. Fabric and NeoForge builds are published, and the code is open source under the MIT License. Arenas_LD requires no other mod.
