How do I use this wand rename?
Log on in-game and wait for the purchase to process - you'll receive a message in chat when this occurs. To use your wand rename, simply type /wandrename. The Wand Rename GUI will open and you can then follow the steps that the GUI explains. Colour codes are supported. If you want to revert your wand name back to its default name or to an allegiance/club wand name, simply type /wands and select Wand Names.
