Matted’s World Arena
This is "Matted’s World Arena", a custom master world with an arena that spans the entire world. The segments of the arena were made in vanilla and the world was produced with TEdit.
It was originally designed for Infernum Devourer of Gods, but can be used with multiple other bosses in both vanilla and modded.
The only biome in this world is the forest, meaning bosses that require a specific biome to spawn or any spawn condition will have to be summoned through the use of mods.
The platforms are spaced ~40 blocks apart, with universal pylons connecting the centers.
