Walkthrough tips, Discussion of Campaigns [Heroes 5]

I advise you to capture the Castle on the left first. Don't be afraid of the Phoenixes standing in your way. Gather a small army and attack, but make sure you have enough to capture the Castle. There are many mines nearby, which the green faction has likely already captured. In this Castle, you can buy creatures of any level, from Dryads to Crystal Dragons, and you can also buy the Castle itself. Then, wait for Gilraen to attack you. You will most likely defeat him there. After that, leave a small garrison in this Castle, and let Agrael go to capture the Castle on the right, since you have probably already killed Gilraen. But don't relax, as there will also be a significant army there. Finally, capture the Castle closest to the Inferno Castle. As soon as you capture it, you will need to kill Gilraen, but since you have already killed him, there is nothing to worry about. However, this task will not be completed if you don't. Buy any hero and disband him, and this task will be completed immediately. And the easiest thing is to kill the Druids; you will receive this task along with the previous one. I repeat, don't capture this Castle right away, as the Druids create Elves who join the enemy. That's how I completed this level. P.S. You don't need to build defenses in the Inferno Castle. The enemy won't attack it.
