He is one of the greatest swordsmen of their time. 
”Arsteel always got to be the mean one,
”It shouldn't have happened. Arsteel was a brilliant duelist— almost as good as Denth. Vasher's never been able to beat either of them.
”Vasher didn't use the sword. There was no blackness to Arsteel's wounds.
”You never beat Arsteel.
Brandon has said that the reason Vasher dueled and killed Arsteel might be covered in the Warbreaker sequel. It's known from annotations that Arsteel didn’t set out to duel with Vasher intending to harm him, but because Vasher thought that was the case, Vasher ended up killing him.
