I never suceed...
It looks like you're fighting the big boss of act one but it's only a random encounter.... Don't know why they're doing things like that...
I sucked hard. In the first time I played Baldur's Gate 2 I didn't finish it. That's how much I sucked. And still, although it is a difficult fight, I don't think it's impossible.
I don't think it's impossible and I love difficulty, but if it's well integrated and if it is consistent.
A boss has to be more powerfull and the combats has to be special.
The first random fight you face in the underdark shouldn't. Combats in the underdark have to be a little bit difficult but here it's probably one of the most difficult fight in the game if you don't exploit it's cheesy mecanics. That's ridiculous.
I think the game should be fine with "normal" and easy combats. The game is balanced for every combats being more or less a challenge and that's not fun. We're not random, let us feel like special and powerfull adventurers sometimes... I don't wanna be the hero that isn't able to fight 3 gnolls in less than 8 turns, with companions falling inconscious against the weakest creatures of the FR.
It's an overdose (the word we should describe BG3 with) of challenge. An adventure doesn't need to be a challenge at every corner to be challenging.
