I've wanted to play this map for a long time because I've heard a lot of positive feedback about it. I knew in advance that the scenario is considered quite difficult, so I decided to start with the lower difficulty levels. As a result, I completed it three times: first on Recruit, then on Warrior, and the third time on Hero. For me, the scenario turned out to be more strategically challenging than tactically. It's a large map, the enemy has many towns and heroes, and portals to towns are prohibited. In multiplayer maps, there's often a situation where you've already killed the strong enemies and spend a long time chasing weaker ones. Here, it's something similar, but much harder: because all the dwarves' heroes are high-level, it's impossible to defend the towns with weak heroes from the tavern. Tactically, everything is more straightforward: it mainly involves standard battles through darkness, but light also helps a lot. There were only problems with individual battles: I lost, reloaded, lost again, and after several attempts, I won... I never fought the neutral Necromancer: on Recruit and Hero, Rolf killed him (on Hero, he also stole archangels), and on Warrior, I just didn't bother with him. During the playthrough, I developed a certain strategy, but in general, you can play it in very different ways (other players' comments confirm this).
My strategy
1) Choose Mariella as the main hero; she moves faster. Natalia gathers resources.
2) Skills: logistics, leadership, darkness, light, defense. It's important to take empathy and path of war.
3) Develop quickly and complete quests (capitol and 300 peasants) to increase the army. We don't fully build the guild because light magic is available in the dwarves' towns, and darkness can be obtained in various ways.
4) At the beginning of the third week of the first month, Mariella breaks through the garrison and begins the invasion. Natalia remains in the starting town.
5) We take the first dwarves' town, sawmill, and mine. We complete the necessary buildings, and Natalia begins training.
6) Now we have to defeat the powerful enemy heroes, enhanced with artifacts (Rolf, Hangwul, Carly). On Hero, I often had to reload.
7) We get many artifacts from the dwarves. The most important ones for Mariella are: a tome of darkness, boots (traveler's and open road), a staff, and a ring of Sar-Iss. We definitely keep the dragon artifacts; later, we might collect the full set (but on Hero, I collected it too late and never wore it). Many artifacts can be sold, and we get a lot of gold. We can now train cavalry without problems.
8) Mariella continues to fight the dwarves, captures towns (but new dwarves come and take them back). The ratio of Mariella's army and the enemy heroes gradually changes in our favor...
9) Mariella alone cannot defeat all the heroes and control the towns, so we also send Natalia to the enemy territory. Now, we run after the dwarves with two heroes. We destroy all enemies and capture all the towns.
10) There is one strong but passive hero left - King Tolgar. We give all the troops to Mariella and win this battle. The scenario is completed!
I enjoyed playing the first two times. Warrior seemed easier than Recruit (except for the unpleasant battles with Rolf and Hangwul), probably because I already knew the map. But the Hero playthrough (I thought about it and removed the overly harsh wording) was more uncomfortable, but no one forced me to play on the maximum difficulty. I want to praise the author: everything is very well done: quests, landscape, plot. I can also separately note two strong points of this scenario:
1) Interesting strategic gameplay. It really requires you to think several days ahead.
2) Beautiful cutscenes. Even today, it would be difficult to come up with and create them. And this is 2014; there weren't detailed guides on creating cutscenes back then!
Results in terms of the number of days: Recruit - 138, Warrior - 90, Hero - 131. I didn't aim to complete it quickly. I took the picture from the Hero playthrough.
Thank you very much for the map!
