Does the "sell all extra units" button sell all the units that are outside your current army or only the units you could never use because of the army size limit? For example, I have 7 warriors outside my army. If I click the button, will I lose all my warriors or only two?
It sells off the extra units that you could never use because of their cost compared to your army limit (1000 points). So in your example of 7 warriors, only two warriors will be sold because you could use 5 (5 x 200 = 1000) in your army at once.
Awesome. That is what I was hoping for.
