Point Blank Master question

[Saldiven]

Is Point Blank Master the only way to make regular attacks with a bow from within an opponent's threatened area without provoking attacks of opportunity?

I'm pretty sure it is, but wanted to make sure.

Feat-wise, yeah. There are certain archetypes that get that as a class feature, such as the zen archer monk. There's also the nimble shot ranged weapon enhancement from Ultimate Equipment, but it's a whopping +4 bonus.

There is also the Air warpriest blessing, and Close-quarters Thrower which is a feat that is the same as PBM but it works for thrown weapons and isn't fighter only.
