I have the Bloodhound's Fang up to level +9. It is a beast! I also carry a Rogier's Rapier +18 with the Flame of the Redmans...two ash special and then enemy knocked down and then stabby-stab, rinse repeat.I've been using the Bloodhound's Fang for most of my playthrough (the Bloodhound's Finesse skill/weapon art is pretty overpowered)...the only bad thing about it is that it can't be upgraded with Ashes of War so I can't really experiment with different ones...for my 2nd playthrough I'm going to try different weapons
