A new accessory called "Naming Tag." Basically, attach it to any weapon, helm, armor, costume, or shield, and you will be able to give it your own personal name. So, you could finally name your Acheron "Katana", your Stone Tortoise "TortoSkeleton", or your Azure Guardian Helm "High Tech Proto Helm". Whatever you wanted.
Upon forging or upgrading a piece of gear, the name that you called your gear/weapon does not change.
These names would show in Lockdown (if you wanted to mock your opponents) and upon Inspection.
If you dislike the name you put on, you do not need a new tag; it is possible to rename your weapon. This can be done infinitely. However, removing the tag destroys the tag, and reverts the gear or weapon's name to the original one.
Additionally, if you trade a weapon that you named, or put it in AH, that name is locked onto that weapon, so you cannot change someone else's named gear or weapon.
This tag may be a rare drop from treasure boxes, or can be bought cheap (around 20ce is what I guess, but I'm not good with pricing SK stuff) from Supply Depot.
So what if I name a weapon with an inappropriate name?
