Confirming Crits

[Onestep]

If you're attacking a monster with a ridiculously high AC, such that it can only hit on a natural 20, do abilities/spells (such as Weapon Mastery/Bless Weapon) that automatically confirm crits still function, or does the fact that you couldn't confirm a crit mean that they don't?

That is, unless a crit confirmation roll counts as an attack roll and another natural 20 would auto-crit? I'm honestly not sure if that is the case though.

A natural 20 on the confirmation roll confirms the critical hit. The confirmation roll is an attack roll, so it auto-hits on a natural 20.

To find out if it’s a critical hit, you immediately make an attempt to “confirm” the critical hit—another attack roll with all the same modifiers as the attack roll you just made.

Diego Rossi is correct but even if that was not the case anything that automatically succeeds is a success.
