Should be able to pass it - I'll check on it. (remember that you select the receiving unit and "take" equipment rather than giving it with the unit that has the equipment?)
With the latest patch (E) my warrior found a ring of perception, and my scout cannot take it from him. Is there a quick fix I can make in the XML? This is annoying In my previous game, when my unit died, the equipment was dropped, so that is one way to pass it.
