"Weak demons"??

Those who think demons are weaklings will have a hard time mastering this castle. Yes, it’s difficult at the start, there are resource problems, and there aren’t many good heroes – all of this is true. However, this is compensated by gating, attack, darkness, hellfire, and creature abilities. Play Inferno more, and you will see its strengths, rather than complaining about its weaknesses. In Heroes 3, short-sighted players also considered this castle weak, but after losing a couple of times, they changed their minds.
