2 Starhan

Agrail was needed by Kha-Belekh because the Griffin Heart has no effect on him, and only he could approach Nicholas and kill him.

.
So, why did he need to kill Nicholas? There were no such orders. And Kha-Belekh would have been much happier if he hadn't killed him.
Regarding Dmm&m. The plot there is not better than in some Hollywood blockbuster. Especially it doesn't fit with the lore of PovOrdy. After all, a hybrid of a demon and a non-demon is an orc. Then why do Sareth and Kane, from the Demilich's story, look like humans? Also,
Sareth, in demon form, becomes faster and stronger.
Mine didn't get faster, and didn't become stronger.
But if allies see him in this form, the game is considered lost. Eh, the only encounter was with a sorceress who said, "Oh, you are so bad," and attacked (by the way, you can just ignore her and run past). The game was not considered lost.
I managed to get through the story, but it's too boring and illogical, and there are a lot of clichés.
