The main character barely managed to defeat him with the help of a summoned bear and a whole bunch of potions.
Hmm, the question is - did you kill him?
I also liked the cutscenes :) There are many of them, and they fit well.
By the way, I started a second game as a Sorceress. This time, I immediately went for Destruction, but focused on Cold. I probably won't use Morrigan at all, or only as a trap/werewolf. There are many options in general, which is very pleasing. It's much easier to start as a mage; the only important thing is not to be passive. For example, the Ogre can be defeated without losing even one member of the group, while as a Rogue, I had to defeat him alone with a rather tedious combo: "stun" -> "hit him in the face 2-3 times" -> run around him in a circle until the cooldown is over." Perhaps this is the only time I used this tedious tactic in its pure form :D I also ran away from Branka, but there a Warrior runs to distract, while the Mage or Mages attack from a distance. The Gnomish scoundrel creates annoying clones there :)

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
