Mythic Critical Focus
Source Mythic Adventures pg. 61
Your blows unerringly find your target’s vital spots.
Prerequisites: Critical Focus.
Benefit: You automatically confirm critical threats against non-mythic opponents.
In addition, when you threaten a critical hit against a creature wearing armor with the fortification special ability or similar effect, that creature must roll twice and take the worse result when determining critical hit negation.
There may be other things that do something similar, but this was what caused me to bring it up.
