PvP Arenas?

[coolwolf9999]

I see on a lot of bending servers pvp arenas that allow bending. How do I do this? They have it so it regenerates the arena every 1 minute. I know this is probably with WorldGuard.

Also they have it so in a water pvp arena they can only use water bending how do I do this too?

For the first part, find some arena plugins. For the second part, I don't think you can.
