ER arenas – New duel arenas.

How do you create dueling or simple arenas?

There is a guide by Zenithale on creating arenas. http://heroescommunity.com/viewthread.php3?TID=29393
I used it when I was learning about this. However, not all aspects described in the guide matched the realities of the creative process. So, I did some things my own way, finding new solutions through trial and error. Try following the guide, and if something doesn't work, you can ask me a question.
