"The Will of Ashan" - "Heart of Darkness" [2nd campaign, 5th mission]

:smile45:
I don't know, maybe I'm the only one, but I can't complete this accursed mission - "Ashes' Will."
I've tried different approaches:
1. I didn't kill the assassins, but sent them to the demonesses, and placed 4 heroes in the circles of the House - nothing happened =(
2. I killed the assassins, placed 4 heroes in the circles of the House, and had an additional hero run to the spirit - it didn't open; I also had all of them run to the spirit one by one, changing their positions - nothing happens.
3. I killed the assassins, entered the portal with the trees, gained a few levels, and placed 4 heroes in the circles of the House - and still nothing happens.
4. I even captured the gold mines in the last portal - still nothing =(

All that's left is to reinstall the game =)

At first, I didn't kill the assassins because I didn't know that they were the assassins that the spirit asked me to avenge. They overwhelmed the succubus, and the secondary quest failed.

I reloaded and killed the assassins. Then I returned to the gate, and the spirit said that for this, he would open access to any one-way portal of my choice. You can only visit one, because after visiting, the rest are blocked again. In one, there are various dark creatures, in another, there are 3 Elder Silvans, and in the third, there is a prison where the daughter of the murdered lord, who became a spirit, is held.

As a true gentleman, Arantir freed the girl. His army with 5 castles was simply huge - 100+ dragons, 1000+ vampires and ghosts, etc. And the archers could take out 30-35 neutral archangels with a single volley. Therefore, he didn't really need the 3 extra levels. After freeing the captive, 4 necromancer heroes took their places for the ritual. The passage to the last castle opened. The battle was very short.
