"Made of a rare alloy of sun silver, knights talented enough to possess Caliburs as fine as this one typically bond with and name their blades."
Yeah, that would be quite interesing. We can name our Battle Sprites, why not gear?
That would be very cool in my opinon. Knights in medieval did that often.
Mine suggestion for that system:
Kozma would sell weapon name change passes for 50-300 energy (around that, more would be bad). It can be used for naming weapons, armors and costumes.
It would be shown in equipment, inspect and weapon wheel. Name of named weapon would be italic, in inspect and under name, there would be visible original name in smaller font.
-Items could be traded with keeped name
-Items' name must be resetable for free
-Naming does not bind item
-There could be free bound weapon name change pass in one of missions
I have a similar idea here.
