Damn, it took me several hours of dying to Behlifet to figure out he's immune to weapons below +3.
What a ridiculous power. What is the point? Why make a boss immune to 99% of weapons in the game? What if I wanna beat him with a knife or even bare-handed? I know many AD&D monsters had these stupid immunities to weapons but it's just unfair to many characters. Anyone who's not with a super rare weapon shouldn't even be there, no matter how powerful.
So, my main character being a katana user, and not knowing about this caveat, I was only lucky I had some hundred +3 arrows and another hundred +3 bullets, all my characters needed to conform to ranged +3 ammo, because I wouldn't ever land a melee attack on Behlifet otherwise. It was a pretty dull combat, 6 guys shooting arrows forever on him while the aasimar was the only one up close. With that setup, beating Behlifet is trivial, but I couldn't even think of picking the alternative of killing the aasimar myself, it would've been unfeasible.
And while we're at, what a confusing, badly executed twist at the end. I wanted to like those last couple chapters more.
