A quick question(s)

Um..first of all, what is the maximum file size for maps that can be hosted on battle.net?
Ok um...
How can I make heroes buy spells from a shop (Like Hero Builder and Buyspell)and have them level every 10 minutes?

I'm still working on Arena of Chaos. It will probably be completed in about 2 weeks or so?

3MB is BNet Limit.

It's just a trigger. Make a one-shot, instant consumable item (Base it on the Runes). Detect it being bought and add the ability to the hero.

Again, just a trigger. "For (All Units in Playable Map Area do Hero - Set Level = 10" or whatever.
