Racial ability: "Preparation".

I'm building dwellings for angels, but I'm not in a hurry to buy them. I'm using a residual funding principle. The main thing is training. If there's money left, I buy angels. I try to level up the hero-trainer – skilled in counterattacks and an experienced commander. It's also good for the trainer to have the ability to gather troops. In Heroes of Might and Magic V, there was no need to train trainers. Isabel is the best trainer in the world. Moreover, she became an experienced commander with skilled counterattacks and the ability to gather troops in the first four missions.
