Simple RAW for Pathfinder Thread VI: Return of the Red Die

[Petrukio]

Q12: Can a Rogue/Monk make a combined flurry of blows & sneak attack?

A12: Yes, so long as the opponent is subject to sneak attack on every attack (is flanked and does not have Improved Uncanny Dodge or the equivalent, or otherwise denied Dex bonus). This is not necessarily always the case - if the sneak attacking monk was invisible (not greater invisible) before he attacked, he'd only get sneak attack on the first attack, all other things being equal.

The only real reason why this might not happen is if there was a conflict in action type, but so long as the conditions allow it, this question is no different than 'can someone with multiple attacks sneak attack on all of them'? Flurry of Blows, like any multiple-attack action, is a full-attack action, and sneak attack does not have an action affixed to it.
