It's nice to see someone using the ItemData system for something unique (for RotMG at least)
--EDIT--
Fun thing about the way ItemData is done right now... I was thinking of re-writing the entire inventory system once... Make it so all items are 100% ItemData, the ID saved in the character information is just things grabbed from another table in the database that would save every single item in the game... I realised soon that I was just crazy and this would only be useful for things like UTs... which I still think is a good idea as it lets items be customized to a whole new point. Maybe someone will look into doing something like it someday.
