Had a quick thought... Shields... wouldn't the world be a better place if some if the things we hold onto scepters for came on shields as well? If sacred can be on a shield, why can't Devotion, Acid Lore, etc? Maybe just Cleric related ones make sense, but...

Speaking of shields, shield of reflection... bounces ray attacks back at the caster... (screw you Mr Beholder!) doesn't work if flanked.

How about items whose traits change as a character levels? Maybe just increase in power, maybe add random (or previously hidden) effects? Binding such items would, of course, be a requirement.

I don't know, just some idle thoughts.
