It refers to each skill, so 10 total skill uses if both are counted. That said, I don't expect most battles to take that long; it's primary purpose is to limit spamming, among other things. 

Your character's good, but I may ask that you repost it in the OOC if/when I make that. 

To anyone else, you don't have to post your character now, you can hold off until the OOC is up. You can if you want to, but it's not required just yet. This is just the interest check, after all.
