[Perks] No critical failure?

[Kazander]

I don't think you need to spend that many points.

I think it would be sufficient to build it something like this:

Ridiculous Luck (Critical Failures only -10%; Effective Skill must be 16 or greater -10%; Own skill rolls only -20%) [36]

This isn't much different than what you are looking for. Once per 10 minutes you can reroll a critical failure on a skill roll, as long as your effective skill is at least 16 (i.e. if you make a Deceptive Attack that brings your effective skill down to 12, it won't help you). If you're playing with multiple people, you're quite unlikely to ever roll more than one critical failure in 10 minutes. As built, this won't help you with any Attribute rolls, or force enemies to reroll Critical Hits against you. Similar to Defensive, but more restrictive.

It's definitely more expensive than a Perk, but what you've asked for is worth a lot more than a Perk.
