1) Regarding the Amulet quest - if you look at the surrounding area, everything will become clear. There's even a message that says "he was defiling all these lands, etc."
2) The game's ending:
a) How did you get through it - by force through the outpost or by a clever method? =)
b) Actually, the finale. Well, I don't even know, I played through my map today (the first proper test, more on this below), found a few bugs, and maybe the ending will be changed in version 1.2.1.
Regarding the testing, I played as Markel, thanks to his skill in gathering undead. The only thing is, there's a mentor on the map; I didn't check if it's possible to remove the leadership, he doesn't really need it, although, thanks to the "Lord of the Dead" talent, all neutrals turn into undead, and I gathered several hundred vampires and had a great time).
In the castle, I didn't get "Raise Dead," so I had to replenish my losses with the second upgrade using a Lich, but then I found the Book of the Dead, and I got through it quite easily, although the General turned out to be very strong.
Now about the bugs:
1, 2) The outpost quest - it will become "Completed," but when the outpost belongs to Player 1, all other players, except Player 2, will not be able to approach it.
3) The shipyard - now you can disembark from the ship onto the lands of Players 4 and 5; maybe this will be fixed, or maybe, on the contrary, I'll make this possibility a standard feature.
4) The strength of the demons on the Hero - I won't do anything about it for now; I don't want to make the map too easy. On EASY, everything can be completed with auto-combat. If there are a couple more comments that it's too difficult, I'll still weaken the General (his helpers are almost the same as in the old version). We'll see.
5) The game's ending - yes, it will probably be changed. Suggest your ideas to make it more interesting: I have an idea to make a battle with Biara, but she will increase her army every week, so you'll have to open the Sanctuary quickly.
Write comments, preferably indicating the difficulty level.
Thank you.
P.S. It would be great to make a "small dungeon" and scatter some kind of assembled artifacts there (parts of the dragon set).
