Well if you're just looking for how to save the data... I say serverside text files is the best way.

I made a system that copied template weapons when a weapon was created, and then saved it to an individual weapon with an ID to a serverside file, where it could then be customized. That made it possible to have weapons that started out as a normal weapon, but could be customized and given stats like dex+1 or such, without needing to actually have a system that managed the extra stats.
