Agree with OP that pretty much every puzzle was mediocre at best. Elemental caves one was probably only good one. But he said it himself. Good puzzles are insanely hard to make. It takes a special kind of brilliance unless you have some amazing mechanic like physic-based portals. Larian should have had more intellectual and dialog-based puzzles that require you to think hard, but not in an esoteric, insanely specific way. But really, if you can do that with any consistency, you're probably not making video games. Because there are so few good puzzles in a vast majority of games.

Divinity for the most part lacks the mechanics for good physical puzzles (Bellegar maze was ugly and boring), with its minimal physics, though I'm sure someone could make it work. But it's fine for intellectual puzzles. But those take a genius. Someone prove me wrong and tell me a good intellectual puzzle they've come up with. Of course, I'll probably not know if you've stolen it from somewhere. But I'll take your word for it and give you kudos. I mean, even finding a really good intellectual puzzle is hard enough. And if you're puzzle is good, maybe it'll make its way into my (future) module smile
