Just an idea here.
I don’t see much value taking CR over Surgical or even Point Blank because the bonus only really becomes worthwhile for the final bullet, and it’s easy to surpass even with a partial Surgical shot.
Normally, I don’t bother discussing possible buffs for individual blessings, but a lot of that’s been going around lately so here’s a stab.
+4.5-6% Critical Chance for each expended round in your weapon (resets on reload). If the last shot in your gun is a crit, you get 1 bullet back in the chamber for free.
This would make it a more unique crit-chance blessing, and be thematic considering most games of Roulette only have one bullet in the chamber, and you’re effectively gambling here. It would also make having two crit blessings a slightly more viable build.
If this is too potent, a cap can be added “This effect can trigger at most X times in a row”
