My girlfriend plays a tengu heretic inquisitor. She has 35 stealth at level 9. So she just stands still and kills everything that comes close to her and they have no idea that she is there. She has a magic item that gives her
ricochet shot so she can hit 2 people with each arrow. In the last fight, she killed 2 level 7 inquisitors, 3 level 5 fighters, and 2 enlarged brawlers (between CR 6-9). And she wasn't touched once. It has gotten to the point where the oracle has had to yell at her to stop hiding so that enemies would fire on her instead of the rest of the group.
This build doesn't do much with swords but she roleplays that not having swords is the reason that she is an out-caste from her family and has thus joined a group of assassins (thus the heretic archtype). She really enjoys the build.
