I'd love to have gnomes be able to give/sell items. It could be used as a vendor, or as for when we have house parties, as a way to give food to everyone (set limits of like one per person).
Actions:
Set Message: Sets the message that the gnome will say when the player clicks on it.
Hold items: bring up a dialog so that you can give items to the gnome.
Once the gnome has items, you can then set their properties of price and limit. It would allow for a lot of different uses, and could be a lot of fun.
