I played on hard difficulty, using a Warrior of Chaos build. Generally, everything is manageable, and I reached the point where I had to face Torgul's army. I saw the "deadly" difficulty notification, so I spent two weeks gathering troops from all my castles. The notification changed to "serious," and I defeated him using auto-battle because I was too lazy to fight manually. Then, I encountered a trap: a battle against Azrael and a ridiculously large army of Zana: over 200 Destroyers, more than a thousand Cerberuses, 800 Succubi and Lilims each, over 500 Imps, and over 200 Fiends. No matter how hard I tried to focus on killing the hounds with "Evil Blood," the rest of the units just overwhelmed me. If I tried to stay behind cover, the archers did less damage, but all the melee units would attack, and the dogs would often catch up and bite. If I tried to block the archers, the infantry would surround me from all sides. The dogs would be blocked, but they didn't even need to be; there was already enough meat there to kill Azrael. I tried different tactics and replayed the battle about 15 times, but it was all in vain. Either I lack the experience for these kinds of battles, or something else is missing. I gave up, replayed the game on the easiest difficulty to finish the map faster, and the final battle was, of course, twice as easy, as was Zana's army. I defeated everyone and still had 28 health points remaining.
