I've been using the Cobalt armor set and the defender
been upgrading.
I'm about to get the solid Cobalt Armor and helm.
I am also using a Ascended Calibur currently and will upgrade it to a Leviathan
My gun a magna
Is my kit decent for a swordsman
Really, if you are going to be a swordsman, there is a much better armor line (Wolver) available to every knight.
Even if you were to consider other piercing armors, there are MUCH better candidates.
Sword's alright, gun's alright. Just not the armor.
