Some Item ideas from Endarire:
Magic Items: Elemental Gems. Break one and spawn an elemental. Very effective when I as GM used highly maneuverable gargoyles to drop them on PCs.
Flying Carpets and Brooms of Flight: Of course!
Wands, Scrolls, Potions, and Staves: Obviously!
Boots of Speed: One of my favorite items from Baldur's Gate.
