Phase 1: I decided to make an arena (More of a Battle Ring at the moment), I will expand this and add multiple layers to it. It is temporarily claimed so it can't be broken and I will unclaim it when people want to use it.
Phase 2: I add more to the arena, Also this is not the final version either. I plan on adding Watching areas and perhaps some tech.
Phase 3: I added a Tesla Coil, Spawning Rooms with a bed and mcmmo anvil in each one, added Slime Pads, replaced nether lava with Pyrotheum, replaced center with custom symbol, added several Ender IO blocks.
