In BG3 you'll often have to make several successive concentration checks in a row, or just get handed an auto-fail that had no chance of not breaking your concentration automatically... The game is tailored strongly to make people hate the concentration mechanic and think that it's bad, because it's extremely difficult and often impossible to maintain your concentration for any useful amount of turns at all.

It did notice the concentration being lost very quickly and sometimes without understanding why but I didn't pay more attention to it (until now).
After a little bit of research on this forum (in addition to what's been said here), I've seen some mentions of things that break concentration but shouldn't : prone, abnormal amount of surface effects and magical arrows (even when missing with Nat 1 and they are given to all sorts of NPCs which is apparently uncommon?).

Is there a proper thread that has made the suggestion that I could find?
I've seen this one : https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=773389
But I wonder if Larian listens to threads with titles like "Concentration Loss Jackassery" 😶
(I hope, because they are some good points there, but I'm not sure they would?)
