Anyone out there have experience with this prestige class? It seems like it might be nice for a 3 level dip for certain melee classes. In those 3 levels you gain d6 sneak, dirty fighting, a lot of class skills, and flag of convenience (good for the +2 bluff checks and no leadership penalties). The dirty fighting is nice - +2 to all combat manuevers, no improvised weapon penalties, and special crit conditions (most of which are pretty good - especially against casters).
I'm thinking it would be nice for a sword & board guy (6th level ranger, 3 level templar), which would give you the sneak on the twf as well as +2 to bull rush. It might also be good for a two weapon fighter with two weapon feint for the +2 bluff and the sneak. If you had a high-crit twf (kukris), the dirty fighting could give you a great chance to keep at least one condition on an opponent for the entire encounter - there's no save. The +2 combat manuevers is nice for several builds.
He also picks up heavy armor and martial weapons, which could be nice depending on original class. The +1 hit, damage, and will saves vs. CE outsides could be nice if you have demons in your campaign.
Mounted combat is a bit of a downside, but other than that qualification isn't difficult.
Anyway, just wondered if someone had tried it out.
