The Purgatorium
The hell inspired customizable server arena!

The arena includes varying terrain heights and a glowstone maze to break up the arena and give users options and availability in choosing attack/defense strategies to keep game play unique

This is a bare-bones PVP or PVE arena!
You will have to do any server protections, spawns, and anything else you find pertinent to the arena's effectiveness will have to be done by the users.

The Purgatorium was designed with Mob Arena in mind, so check it out!

Creation
This was created for personal use only, and created and originally designed by me, Brisbe25 with additional suggestion from joecoolkim.

The floor of the arena is created using World Edit, the archways and everything else were hand done

Feel free to use this in personal servers and maps, however in doing so you agree to giving me credit!
(Youtubers especially!)
