My tool (below) allows a "Warrior" and a "Wizard" to each spend 30 points in 2 areas.
How can I limit the amount you can spend in a single area to 25, leaving 5 for the other?
I would do something like this: [jsBin]](http://jsbin.com/ukeMiFe/1/edit), which categorizes all powers, items and gives them costs so that the logic can decide if it's affordable, usable and what the benefits are.
