As per the subject of the thread, here is a Two Weapon Fighting Mounted Rogue Build Mini-Guide I made.
The concept is this:
• Use the Eldritch Heritage feat to get an animal companion you can ride; and
• Select a number of teamwork feats that allow your rogue and his animal companion to have a permanent flanking bonus and grant each other additional attacks.
The main selling point of the build is the fact that, from level 8 onward, and as long as:
• you are mounted;
• threatening someone; and
• that someone does not have concealment;
you are always flanking, which means that every single attack you make is a sneak attack!
In other words, your sneak attack damage does not depend on having other party members flanking with you and the fact that your enemy is flat footed or not is completely irrelevant!
For at home games the build requires a certain degree of DM approval regarding some Feats (which are not included in the Core Rulebook) and specific magic gear (Horsemaster’s Saddle from Ultimate Equipment or the Sky Marines Elite Saddle from Pathfinder Campaign Setting: Inner Sea Combat).
The other selling point of the build is the fact that the core of it is completely legal for Pathfinder Society Games, according to the Additional Resources list, as at January 20 2016!
Lastly, I’ve included build variants based on both the Core Rulebook Rogue and the Unchained Rogue.
I heartily recommend that you use the Unchained Rogue as the basis of your build, because Finesse Training (add Dexterity to damage with your selected weapon) and Debilitating Injury (reduce opponent’s Armor Class and/or Attack Rolls with each hit) are awesome!!
Enjoy!!!
