Here are the scenario weapons for the Swordmaster from Rank 40 onwards. I've found it good to know what I'm aiming for :) Click to see larger images. I owe a debt to Gaar.
The Titan Blades are the offensive choice, Sentry defensive. I'm currently gunning for the Invader Defensive 2H. Weapon DPS contributes a lot to some key SM abilities (like Ether Dance) and Strength less so.
What weapon are you using to drive the foul taint of Chaos from the shores of Ulthuan?
