Uninvited guests.

Hello! I played a bit as the Barbarian, and it turned out to be difficult for me (I couldn't withstand the second wave of attack; the heroes attack the castle one after another). In a short time of playing, I noticed one flaw – it's impossible to recruit creatures in the "Hall of Shields" (I was playing as the Dwarves). Later, I'll try to start over and will write back. Thank you for your work!

Hmm... The game time is 19 months... I've already captured 4 castles, and no opponents are bothering me anymore, but (!) the game has reached a stalemate – the passage to the bridge leading to the last (as I understand) castle is blocked by 11,000 devils, which I can't defeat with any known method. Perhaps, you can cope with such a crowd by using spells like "Frenzy" or "Puppet Master," but for some reason, none of the heroes I've developed have mastered these spells.
What do you advise, friends?)
