In addition to what the others have said, I think degrees of failure are often a fun thing to introduce whether they are in the rules or not (I’ll assume D&D 5E). It might be that a 20 with your +3 athletics isn’t enough to completely leap over that huge gap, but you manage to grab a handhold a few metres below the edge. You’ll have to take a turn or two to climb up, but you’re okay. The cleric’s roll of 3 with a -1 athletics, on the other hand, sees him plummeting to the bottom and taking a heap of fall damage

They do at my table. Because it’s more fun, god damn it!

Taking a 10 is a strategic choice. You can automatically succeed because the DC is >10, or you can roll for it and try to get a critical success that comes with a random fringe bonus (such as extra XP, or making an action more permanent; like you crit a lockpicking check which just breaks the lock so it can’t be relocked) but also with the chance of critically failing (you broke the lock and now it can’t be unlocked!).

It also allows you to maybe succeed even if your stats would not let you. The DC is 50. With your bonuses, even a 20 would not beat the DC. But maybe fate intervened and you got lucky as fuck. Disco Elysium uses this a lot. Hell, there’s a whole sidequest locked behind a door that can only be opened if you roll a double 6.

I have zero regrets about my sick-ass backflip.

Why the hell not? You’re the DM. Why do you not have copies of your player’s character sheets?

D&D is that way, though. Every time you see a natural 20 for anything that isn’t an attack does not automatically succeed unless people are using homegrown, which they often are.

I think we’re talking past each other here-- everyone is saying it SHOULD be a rule and everyone they know does it anyway so it’s “part of DND”.

It’s like stacking +4 cards in uno. Might not be in the rules, but everyone knows to do it.

2 things:

1: I’ve gotten disco Elysium, and Ive only played a few minutes, but I don’t remember it having rolls like that? How does one know what one is rolling? I played like 20 minutes of it 3 months ago, so maybe I’m misremembering.

2: that’s how my brother DMs. I once critfailed a lock picking so badly that my character broke his finger. My brother laughed his ass off

A lot of dialogue points and other actions will bring up a thing that rolls 2 D6s. Snake eyes is a critical failure, double sixes is critical success. The earliest point in the game where you can make one of these rolls is in your hotel room. Either by attempting to get your tie out of the ceiling fan, trying to piece together what happened with your shoes by analyzing the broken window, or by using the mirror and trying to stop making “The Expression.”

Many of them can be re-rolled later once you get more skill points. Others are one and done unless you reload or start a new game.

Not to mention which game you’re actually playing.

I regularly play in groups with eight player characters, Kolkani. Do you want me to check all eight of their sheets and all their abilities that could possibly modify their scores or just ask them to make a Blah (Foo) check check and see what the result is? It’s gonna be way faster for everyone to just ask them to roll.

Having that 1 player being stalked by a horny dragon for the rest of the game, just in case.

How do you create fair encounters without knowing your player’s character’s stats? 🤨

Think of it from their point of view though. They want to try and do something. For me to just flat out tell them “no, there’s no possible way” is discouraging and robs them of autonomy. Obviously for crazy extreme circumstances I won’t let them, like “let me convince the king to abdicate to me!” type things. But if I think the DC should be 25 or something I’m not gonna bother wasting my time calculating what the theoretical maximum could be for the roll because I genuinely cannot know. The player can always do things I don’t expect or use other players’ things to help. For reasonable but implausible things I’ll allow rolls even if a nat 20 wouldn’t work because I’m not calculating what a nat 20 could theoretically be.

Plus, I often give people little flavor benefits for nat 20s even if they don’t have mechanical success.

Throwing whatever you please at them. It’s fair because they’re informed of the risks and given opportunities to adjust their plans.

20 peasants stand on the edge of the Grand Canyon and attempt to jump across. On average, should one succeed?

I agree. In casual play you can rely on veteran players to know their stats. If they’re the type to lie intentionally then they can leave the table. If they’re making mistakes then maybe something goes a little too easily, oh well. The best DMs i had didn’t give a shit and focused on rewarding players for learning.

This. You only need dice if the odds are dicey.

Hello fellow Pathfinder!

On page 242 of the Dungeon Master Guide 2014, it describes crit successes and fails as an optional rule.

As optional as multiclassing and feats.

Dating back to 3rd critical skill checks in D&D suck because a lot of skills are written as pass/fail.

Example: picking a lock. If we want to add criticals, a 1 breaks the lock; mostly okay, with the long acknowledged fringe problem of experts being incompetent 5% of the time. What does a natural 20 get? I adore opportunities to be creative, but there’s not a lot better than, “You did it perfectly.” A regular success earns that according to the rules, I don’t want to take it away. A speech about how cool and ninja the PC is can come off pretty cringey to me. The correct mechanical answer would be to let the 20 roll over to the next check because the PC’s in the zone or whatever. Not awful, but it doesn’t directly reward the player right when they rolled the 20, which is the occurrence we want to feel good. We’re also rewriting several rules at this point.

Meanwhile, PF2e baked degrees of success into everything. On a crit fail they break the lock, on a fail they leave traces of their fruitless efforts, on a success they get one success toward opening the lock while scuffing it up a little, and on a crit success they get two successes and leave the lock looking pristine. The players don’t feel cheated when they get a normal success and scuff up the lock. The 20 has some reward for most characters. The 1 has a setback, even a reasonable setback for an expert with a +25 trying to open the DC 10 lock on Grandma’s rickety shed.

I actually don’t mind pass/fail skill rolls in D&D or other games. Rolling a 20 is inherently satisfying to me. But I adore the DC+10 critical threshold for making a good build feel like it was time well spent, in or out of game. And since the natural 20/1 and critical rules are connected at the hip, I’ll gladly take them both.
