The Shadow Judgment assassin attempts to combine the Guild Wars world's two greatest foes- Area of Effect damage and shadow stepping: and succeeds admirably. Combining degen in the form of burning is just a cherry on the top of this sundae of decadent bravery.
This gem comes from the festering filth-hole we all know and love: the PvX authors. Not the "my wife's little sister is pretty hot" kind of love and impure thoughts but the "me and you, with a half-empty bottle of Baccardi, a 40 weight, and wearing nothing but contented smiles" kind of love. The kind of love that only the Shadow Judgment assassin and the original brave man-creator can give to you. Now, the author has since been lost to the annals of PvX:WELL but rest assured that this bad boy will just pop right in behind you and judge you for all you're worth.
