You seem to misunderstand the purpose of dice rolls. The point is to make the game interesting by potentially giving you different outcomes than you expected.

When you savescum you work against the core feature of the game, of course it's not going to be as fun.

Your experience is your experience. You don't like the game, that's fine.

I will say two things - BG3 today is a substantially better game compared to release day in August. Better performance and fewer bugs. Not perfect, but excellent. I have no doubt they'll keep improving the game so it'll get even better in a couple months.

And second, it's ok not to succeed on dice rolls. It's just a different path you're taking. It may feel like you're losing out on completing the whole game, but you're not. In fact, you're missing out on a path whether you succeed the roll or not.

But if it really matters to you, do what I did. I picked a bard who's excellent at persuasion and lock picking. To top it off I got the amulet that allows the wearer to cast the Guidance cantrip (adds 1d4 to all rolls). I basically never lose a roll and if I do, I usually have Inspirations that allow me to re-roll. That might be closer to the experience you're looking for.

You know you don't actually have to pick locks. You can just smash the chest. It doesn't break any of the items inside.

Also, the character stats are important to pay attention to. No one character is going to be good at everything.

>It's a feature of the game. Not a bug of the player.

But it's just not. It's the opposite. Actions have consequences, that's the entire point.

You will never fail a dice roll that prevents you from progressing in the game.
