Worshipper – “Ship” [Campaign 2, Mission 4]

Guys, approximately how many demonic troops are needed to capture Erivell?

I have fresh memories of this Walkthrough...
1. Lower Elven Castle. (money, mines - you can only mine sulfur).
2. By the end of the first week (6-7th day) - capture the Shio Castle in the Dungeon.
3. Replenish troops from the castle and move upwards towards the dragons.
4. Dragons - attack.
5. We go up, and here the most interesting part begins - a serious group is stationed in the castle. The most serious thing for me was the allied doggies.
Just for fun, I put it on auto-battle - after 3-4 turns, the computer offered to surrender.
But this game isn't Might and Magic, is it? :D

The main thing is to have enough troops to withstand a certain number of turns under the castle's arrows (I didn't develop the ballista, as I remember from the past).
And it's desirable to have a berserker in the book. ;) First, attack the archers (because they were eliminating one (any!) stack at a time). After they are defeated by the nearby druids - unicorns, ents, dragons.

That's all.
