Additionally, magical gear like, say, a Cuirass of One Thousand Souls, should be able to be equipped. Honestly it would be kind of cool if all champion's gear was handled piecemeal and objectively rather than a one-time abstraction like normal soldiers ... or to allow for a re-equippage of the abstraction at least.
The only problem I forsee is that your Sov has Magic Plate +1, and you want to equip Magic Plate +3. After you equip the +3 youll probably want that Plate +1 available for another champion. This is why I think special items and CHampion equipment should be kept in some global "storage bin" when not in use.
Sure, I could forsee a problem of two Champions on opposite ends of the globe constantly switching out gear with each other ... but honestly I think thats the exact point of abstraction that I want. A global resoviour of items, so item's don't get lost in some complex mechanic. The only alternative I see is for each city to have a separate bin, so if you are out roaming around, you use the bin of the City you own that is closest to you. In this way, there is still a significant lack of micromanagement, and gear availability is more regional.
I suppose I might prefer the separate city system, but I would prefer the Global bin rather than not having anything at all, so this is my prime suggestion (the global bin).
