Critical vs opponent ac?

[Arashi Kirito]

Ok, so let's say I have the feat that doubles crit range on a wakizashi, making it 15-20. If I roll a 15 but it's not enough to hit the creature it will miss since it's not a natural 20 right? Or do I still get a confirmation roll bc I rolled a crit which might then give me a chance to have a roll high enough to hit? I'm pretty sure it just goes as a miss but wanted to double check.

You can't crit unless you hit. Even if you rolled within the weapon's crit range.

[Drejk]

Only natural roll of 20 on attack roll is automatic hit. All other results must actually hit the target before you roll for confirmation.

[Kazumetsa Raijin]

Any natural roll of a 20 is an automatic hit. A roll to confirm should follow.

If you roll in your critical range, your total must still be enough to meet/exceed the targets defenses. Then, you may roll to confirm.
