Criticals: I know that the player handbook for 5e says that critical rolls only matter in combat. But that is boring. And even then, underimplemented in the current combat system. Critical rolls should be more impactful. At my table when my player rolls a critical roll, it results in the absolute best or worst outcome of the requested action. If they swing a weapon and roll a 1, maybe they drop their weapon, a 20, maybe their attack knocks the enemy prone or severs a limb. On ability checks, a 1 might break their lock pick whereas the 20 opens the lock with relative ease. Have fun with your criticals that's why they are called criticals.
Not to be rude, but when creating a game for the masses no one really cares what happens at your table. I have zero interest in your homebrew creeping into BG3. They have too much of their own homebrew in the game as it is. Fumbles aren't a part of 5e at all and lock picks break on any fail and Larian is already doing critical failures on skill checks which is also not a 5e thing at all.
