I've had this build in my back pocket for a while now (originally located here) and finally have a chance to possibly play it. I'm curious as to how the unchained rogue would alter the build. Let me post the concept and then I will get into the details:
Slayer 12/Rogue (Thug) 5
(1)S1: Weapon Focus (Kukri), Dazzling Display
(2)S2: Two-Weapon Fighting (Combat Style Talent)
(3)R1: Intimidating Prowess
(4)S3: Fearsome Finish (Combat Trick talent)
(5)S4: Killing Flourish
(6)S5.
(7)S6. Imp TWF (Combat Style Talent), Violent Display
(8)R2: Disheartening Display (Combat Trick Talent)
(9)R3: Improved Critical (Kukri)
(10)R4: Bleeding Attack Talent
(11)R5: Dastardly Finish
(12)S7:
(13)S8: Powerful Sneak Talent, Merciless Butchery
(14)S9:
(15)S10: Critical Focus, Assassinate Talent
(16)S11:
(17)S12: Gruesome Slaughter, Deadly Sneak Talent
Obviously, the first concern would be the rogue talents as some of them aren't available with unchained so some modifications will need to be made there. I wasn't particularly keen on taking powerful/deadly sneak anyway, so those will certainly need to be replaced. Secondly, the issue of dex to damage. At first I figured I would just ignore it, since this build is primarily based on strength and buffing my intimidate using intimidating prowess. Also, with this planned level progression it wouldn't come into play until level 9. Thirdly, is the consideration of the intimidate skill unlock from rogue (which, again, with this level progression wouldn't come into play until character level 11). I'd probably just ignore it as well, since my feat progression combined with thug basically enables me to do the same thing.
Lastly, in order to save myself some feats (since I am planning on using this build as a non-human) I figured I would take a page out of STR_Ranger's TWF Ranger concept and go with scimitar/kukri using his glove of storing and 2H power attacking with the scimitar for AoOs, charges, etc. My only concern there is I won't have the planned weapon focus from this build and, on the flip side, I won't have the FE bonuses from Ranger, so my to-hit might suffer.
Please, if you have any ideas on how to make this feasible, chime in. Obviously, I've put some thought into this, but I still feel like I have a lot of kinks to iron out in order to make this thing work. Thank you!
