As a standalone plugin from my main (GooP), it is way too much effort to make a single build be compatible with anything other than the latest MMOItems release.
For the version that spans MMOItems 3.2 all the way to 6.0, get GooP :v
I seem to have forgotten to check if the item being shift-right-clicked was null before checking if it was a MMOItem (and then if had the Hat Stat enabled and so on)
