Something that creates a configurable sized region that neither the Wither or its projectiles can escape. The intended use is for building a colosseum or arena for fighting the Wither.

i think this exceeds the scope of the mod. This feature should be its own mod.

I've thought about this for a while now and I'm not sure how this could be implemented in a configurable way without making it too confusing for players or too complex in code.

I also dont want to add too much bloat to torchmaster. TorchMaster is about spawning control and lighting. But let this discourage you. If we find a suitable way to implement this, I'm happy to do this.
