Sap master & offensive defense

[LordDeath666]

Does the feat sap master and the rogue talent offensive defense synchronize and work together.

[Seto]

I don't see why it wouldn't. You're rolling twice as much sneak attack die on a melee attack, so you get twice as much AC bonus for one round.
Not sure if it's an intended interaction though, and Sap Master is already pretty powerful as it is, so I could see a DM deciding not to allow it.

[Kurald Galain]

Yes they do.

The catch is that Sap Master requires your opponent to be flat-footed (not just flanked). So it doesn't just automatically apply on every sneak attack.
