Fudging a roll is for when I, the DM, realise I made a mistake. No, I didn't realise this creature got a sneak attack until after I rolled that 20!

Legit, I don't fudge rolls because it's not fun for me.

If a roll would fuck up the session/adventure/campaign, I just straight up tell the players I'm making a call and override the results. It doesn't happen often, and it's really only when rng just screws things, like when you get multiple nat 1s in a session, way out of line with what makes sense without some kind of gymnastics to explain things in game.

I love fudge, but too much of it isn't pleasant.

I just like the sound they make. Low key asmr

I have just the die for such an occasion...
