Fade Touched Siverite (Guard on hit) is fine. Fade Touched Fustian Velvet (Hidden Blades) is fine, Fade Touched Dawnstone, (5 seconds of walking fortress) is great. Snofleur is eh. I don't find it to be that great.
You can go with crit or flat attack%. The benefits of crit is that it works better with crippling blows, shield breaker and flow of battle, as well as providing more damage under the effects of the Mighty Offense Tonic.
The best 2handed weapon for crit is the Ornate Battleaxe schematic which can be farmed out in the Enterprise du Leon. For flat attack percentage, the best schematic is the Hossberg Twainer which you can fill every slot with attack%. You can buy this schematic at the keep store in the Enterprise Du Leon.
As for armor, anything works. I prefer superior prowler because it provides more dexterity and thus, more damage for you, but you can prioritize magic defense, stagger on being hit etc.
You'll also want some kind of heal on kill ring or belt. (ring of Life Drain?)
Also charging bull is your friend.
