Made some changes and I'm still working on the Formatting for the forum profile but here's the nicely formatted google doc Gavin Quick
Background is there, I ended up swapping out Bladed Brush.
Combat build wise he's always astride his wolf mount and preferably after drilling the entire party on the benefits of outflank (making flanking +4.) Since he and his wolf have pack flanking they always get the +4 to hit as long as they both threaten a target and more importantly flank which lets Gavin get hit sneak attacks off at all times. He uses Prianha strike, the rogue dex to damage, combat expertise, and challenge to hit much harder and thanks to rogue levels can debuff further. The wolf can trip adding another layer of shutdown.
Background is that of an ex-slaver/spy for the Bellflower Network groomed to be a sparring partner for his Hellknight Master's sons to beat up hate and ultimately kill. Gavin was trained to be an adversary and one of the Hellknight's son's first kill but it didn't work out that way. Don't mess with halflings man, that stealth bonus will kill you :D
