I use the Purity’s Edge Greatblade, picked up in Bastion, for my character’s sword. One, it modeled after the Argent Dawnstar and he is roleplayed as a Captain in the Argent Crusade. Second, if you look closely at the middle of the blade there are carved runes. The blade speaks to the duality of my character- who fell in the service of the Argent Crusade, was brought back as a Death Knight, and has fought his way back to being able to use the Light, though it does cause him pain. So these runes down the center of it I have representing Frost runes, a few Holy sigils and he has one Death rune, which he is learning to use solely to heal himself or other undead companions.
I don’t have any cool names for it though.
He also carries a Light infused pistol on his left hip, a libram on his right, and two short swords, one Light infused, and the other Frost infused. He is also learning a bit of Frost mage skills, as well as Holy Priest skills. Not that he will ever become proficient, but enough to develop some ranged abilities.
He’s a walking arsenal.
