Walkthroughs for custom maps.

I'll try to comment in parts, I don't have time for more right now. Caitlin doesn't need to be lost, actually, she should be kept – she brings in some money. She bounces back to the tent without any problems. I didn't understand anything about Craig. Where did he get the sniper bow? In the editor, it's visible that he has nothing.

I didn't think about Caitlin. In several attempts, the computer killed her. Probably, this is related to which hero you free and whether the computer can reach Caitlin or not. Keeping her will allow you to accumulate some money.
That's right: Craig is empty in the editor. The sniper bow is not equipped on him, but is in his backpack. That's probably why he's empty in the editor, but actually has the item. In general, I opened all the prisons on this save and carefully examined the heroes for skills, and that's where I noticed the sniper bow.

I played as Orin, the Castle is taken on day 117. I don't remember exactly what bonuses it gives, but it seems like the increase allows you to climb through the sea and take the Utopia.

On day 117, we still won't be able to build the Angels, as far as I remember, either we won't have enough money, or we'll have to build a Fanatic building. The Utopia is useful on that map in terms of money, of course, but a couple of days earlier or later – it doesn't matter. Orin is also a good choice, I wrote about it in the review. If you free Orin or Craig from that respawn early (as you did), then it makes sense to take the Castle on day 117 and build Fanatics there, because you will need to leave from there with an army very soon, and it is desirable to have a larger one.

To be honest, I somehow missed that Keir can go to the central respawn through the teleport. So I waited for Gird to break through the green tent on the second month. This was a fiasco)) I also ignored the trick of buying out the Crystal Dragons. On the third week, Gurnisson freed Vey, took the Inferno in the lower right corner of the map and the blue tent. And on the fourth week, Orin with the bonus from the Castle easily dealt with Ivor, etc.

Actually, now I've thought about it, and I agree that Gurnisson's trip to Vey and getting the blue tent is very efficient. The point is that this allows you to free Orin (Craig) very early, and he will crush Ivor himself with the Archangel bonus, or Ellesar will do it. It seems I underestimated this. I remember that it seemed risky to send one hero there and wait for a long time. Although that's exactly what I should have done.
You definitely need to buy the Crystals, because there are almost no armies for war at the beginning, and the fact that the Crystals have hit points allows you to simply pass many battles in expert mode with healing! Plus, speed, the ability to absorb a lot of damage, magic resistance, etc. – all this forces you to buy them. At least for the first few months. Then they will be useful in few places. I also saw this on a couple of Chinese maps, so I decided to buy them.

It's not clear how and with what you fought the bulls before boarding the boat on the cursed land.

The fight against the bulls is not difficult, you just need to replay it 10 times, no more, to understand in what order to finish off the stacks and who to lure where. The landscape is great against them, mass slow, bless on the Grand, and the Pegasi finish off the weak stacks – either themselves or after removing the debuff with the Fly spell. When there are 2-3 stacks of bulls left, you can simply lead them with the Fly spell or Pegasi back and forth. I don't even have a special save for them, which means that the battle did not cause any difficulties during the playthrough. Here is a screenshot.

Thank you for your feedback. Even after completing the game, it's interesting to know how and what could have been done better :) For those who want to play this map: you don't necessarily have to do it as written in the walkthrough or as the author intended. The intended goal can be achieved in different ways, with different methods. There is no single option, and that's the charm of the map.
