Bypassing Sneak Attack Immunity

[KunoichiSong]

So in Pathfinder there are quite a few enemies immune to sneak attack/crit.

Is there any way to bypass sneak attack immunity other than through the Student of War prestige class?

[Gisher]

Quite a few enemies? Elementals, Oozes, Swarms, and Incorporeal Undead are the only ones I can think of off the top of my head.

[Tarik Blackhands]

Aeons are also immune but I don't think anyone gives half a toss about Aeons.

Anyway, nothing really springs to mind, definitely not anything cheap or easy to access. Ensure you have ways to contribute outside precision damage I guess.

[Gisher]

Yes, I forgot about Aeons.

I'm not sure, but a Swarmbane Clasp might let you deal precision damage to swarms.

[Belafon]

For things that are literally stated as "immune to precision damage" there is very little you can do.

Ghost Touch weapons have full effect against undead. Swarmbane Clasp lets your weapons do full damage to swarms "regardless of the swarm’s immunity to weapon damage."

If you can't sneak attack it because it has uncanny dodge or can't be flanked (but can still take precision damage) there's always the hunter's surprise advanced rogue talent.

You could use one of the means to perform a combat maneuver in place of a sneak attack.

In PFS there's a chronicle boon that once you charge up will let you sneak attack elementals a few times.
