Could a ranged Sap Master build deal out ridiculous amounts of damage using blunt arrows? It seems like it could, especially with an Unchained Rogue.
If you went the Shatter Defenses route though, how can you reliably make opponents Shaken? The normal routes (Enforcer, Cornugon Smash) don't work with ranged weapons. The Omen trait is the best I've found, but it only works once/day.
Human Rogue (Swashbuckler archetype with longbow proficiency)
1: Sap Adept, Bludgeoner
2: Weapon Focus (composite longbow) [through Weapon Training]
3: Point-Blank Shot
4: Dazzling Display [through Combat Trick]
5: Sap Master
6: Shatter Defenses [through Combat Trick]
7: Precise Shot
8: Intimidating Prowess [through Strong Impression]
9: Rapid Shot
Any other good ways to make opponents shaken? Any ways to strengthen the build, perhaps multiclassing to get the archery feats sooner?
