I have the glamour prism and am worried that I will transfer the wrong item to the wrong item. I.e.
When I click the prism it gives me choice to "convert", so does that mean that is the item that I like more than the other one and want to convert that item to my older one?
Or does that mean that I want to convert my old item to a new one?

I am worried to change the wrong item to the wrong thing.

At another spot it says "cast glamour"

So I am thinking maybe I click "convert" on the old item
and click "cast glamour" on the new item
or the other way around?
