Set Up Your First Battle Arena

Finding and Throwing the Eye

Locate a Gateway of Doom eye in a structure chest or obtain one from mob drops. Travel to a flat, safe area in your world—a cleared platform works perfectly. Throw the eye like you would an Eye of Ender. It will scan the ground and create a floating portal at a suitable location.

Configuring Your Battle

Once the portal appears, open the main menu with /doom to customize your arena before starting. Choose your difficulty level (Easy for Overworld mobs, Medium for Nether, Hard for End). You can adjust the number of waves, mob types, and timer duration. The mod automatically prevents mobs from spawning inside walls, lava, or water, so your arena is safe to build in any biome.

Starting the Fight

When ready, interact with the portal to begin. A boss bar appears showing your current wave and remaining time. Defeat all enemies in each wave before the timer expires. Mobs stay confined near the portal and cannot escape. Survive all waves to claim your rewards, or fail and receive status effect penalties.
