Well, I guess using Larianbrew comes with the connotation/misunderstanding of that it was a Larian invented homebrew, rather than something that's existed for awhile in smaller spheres (Or larger, as I now know).

Which, in my short google searching, didn't show it was any sort of popular rule (i.e. didn't find anything) and I'm also rather an outsider to TTRPGs, so I just figured it was a rather unpopular rule and something that Larian decided to popularise/strongly utilize as iirc, "Failing is Fun" was tagline for the game in EA.
And for Games, I've only got Pathfinder, which doesn't have it either? (Although, I swear I Crit failed a Skill Check in Wrath once, but I could be remembering wrongly)

And yes, that was the implication; I can understand why for the randomness factor for a run (and the tagline) but I also don't want to deal with it ever again.
