About Fly or Dead Arena
This is an arena. (Arena tournament, Zipline, copy-paste plugin required)
You can spawn it and customize it to your liking. It's a JSON file, so working with it directly in the game is no problem.
To officially use it in battles, it must be added to the plugin. You can choose any name for it.
(This arena requires the Ziplines plugin. Since copy and paste doesn't copy the ropes, you have to reposition them after placing them.)
