Game mechanics of luck (lowercase) passively affecting a character?

What you can have is a perk, allowing criticals on a 7, but making 16+ a critical failure.

Actually, I didn't intend for criticals higher than 6, but rather some effect on the possibility of getting a wider/narrower crit range in addition to normal skill modifiers. Also, perhaps some adjustments to the 3d roll for the type of critical.

I think me that "rrrroll one die extra and drop one" at sixty points be fine. Wishin' and Cursin' modifiers from Visualization can mayhaps be plied 'pon it ferrr effects 'pon yerrr mates orrr foemen rrrespectively, says I.

If you do the math, you'll find that the 4dc3 mechanic boosts the odds of criticals a lot. For example, the change of a 3 goes from 1/216 to 21/1296, a 3.5x boost.

It sounds like what you might want is a bonus to non-attribute tests. Something like the global bonus of the Bless spell in magic.

I don't think I'm parsing this right. What exactly are a wide/narrower crit range, if not more numbers to get a crit on?

One idea I had is that you could look more at the dice themselves. Any non-18 triple is a critical success, for an example which adds fewer crits than counting 7s, or a +2 bonus on any roll in which two dice show the same value. Since we've more-or-less agreed that 50 is a fair value for +1 to all rolls, you could price the latter by multiplying 100 by the chance of a double happening (which I have no idea what that chance is).

The latter suggestion definitely hits #1 and #3 of your requests, and I'm not sure whether or not you'd call it luck-related, so it might hit #2 as well.

What I mean is stuff like having a 6- crit range despite only rolling against a 14.

Or, for below-average luck, having a crit range of 5- even at skill 16.

Some sort of way to modify these things.

Though the best thing posted so far was this:

Roll 4, keep 3 is really quite strong. It's a solid (about +1.5) bump to success chance, a huge increase to critical success and a massive drop in crit failure chance. If it applies to all success rolls, I'd charge at least 75. If it also applies to hit locations, critical result tables and the like, then at least 100.
