Admin Command Reference for Custom Boss Arenas

Arena Navigation and Setup

Server administrators and mapmakers can manage the Annihilation encounter without relying on natural structure exploration or tribute items. Make sure cheats or operator permissions are enabled before running these functions.

• Configure Presets: Run /function annihilation:admin/_/set_config before starting the event to open the settings menu and lock in Vanilla (800 HP), Modded (2500 HP), or Heavy Modded (8000 HP) stats.
• Locate the Natural Arena: Run /function annihilation:admin/_/tp_to_portal to teleport directly to the generated Corruption Portal.

Spawning Controls

Depending on where you want the battle to happen, choose between the two summon functions:

• Standard Arena Spawn: Use /function annihilation:admin/_/summon_at_portal to trigger the boss fight inside the Corruption Portal structure.
• Custom Arena Spawn: Stand at the desired spawn point in your custom build and run /function annihilation:admin/_/summon to summon the boss at your exact location.

Managing Participants

Keep in mind that having more than three players within a 64-block radius will automatically scale the boss's health upward. If you have referees or spectators inside that 64-block zone, apply /tag <player> add anniR.immune so the boss ignores them and deals no damage to them, and use /tag <entity> add anniR.target if you need to lock the boss onto a designated tank.
