So right now, I currently have all of my swordsman gear at 4 stars

-Ash Tail Cap
-Ash Tail Coat
-Dark Thorn Shield
-Dark Thorn Blade
-Avenger
-Gigawatt Pulsar
-Freezing Vaporizer

At this point, how should I go about upgrading my gear? Do I go for the Vog Cub/Coat recipes with the Barb Thorn Shield for its bonuses, or should I focus on getting a Divine Avenger for a significantly improved charge attack and a Shivermist Buster for a much greater freeze radius?
