Hmm, colleagues...
Let's take a closer look at the battlefield...
In each castle, we have one or two "bulky" units, and all the others are single-cell units :d :d
Therefore, the conclusion is - we take four more, one to act as cannon fodder, just like in the second game. On the one hand, this isn't great - I want to use them all! I'll have to think about who to take into battle. I really hope that Nival will reconsider...
On the other hand, I'll still run around with just dragons so that everything else doesn't slow me down :d
