Custom Mobs Addon
Four ready-made arenas for the Custom Mobs raid bosses
This addon does not add new mobs. It gives you finished fight spaces for The Eye, The Greatest Knight, Ragnis Tharkon, and Gorgon. Paste or import each area, spawn the matching boss in the center, and the raid has a proper stage.
How To Use
Install Custom Mobs and all four boss packs, then place these arenas in your world. Start each boss in its matching arena. The layouts are sized for party-scaled fights and add spawns.
The Eye Arena
An organic, crimson chamber built for wide eruptions, nova beams, tornado pulls, and mixed minion waves. Open space so players can spread out when the Eye starts channeling.
The Greatest Knight Arena
A dark stone pit lit by soul fire. Crossed blades on the floor, room for sword minions, turrets, and phantom pressure. Built like a corrupted gladiator ring for a duel that does not stay one-on-one.
Ragnis Tharkon Arena
A nether cavern stage with lava falls and a glowing ring floor. Vertical space for aerial fire, ground combat, and magma minions.
Gorgon Arena
A void-rimmed circular platform with ruined stone galleries. Clean lines and open floor for Gorgon's piglin squad and brute axe pressure.
