Fun items
Luck blade -wishes and save bonues, and good fortune.
Assuming no wish items, a ring of elemental command. One of Fire could protect against a lot, while Water allows you to walk on water and breathe water as much as you want.
Lots of fun with a crystal ball with either detect thoughts or telepathy.
I thought about a Helm of Teleportation, it could be fun. Until I roll a miss chance and die.
If going cheesy, take any of the above, make it intellegent, with the special purpose of protect the wielder, and give it the 99-100 roll ont he table - can do true ressurection on wielder once a month. Woo hoo, no death except for old age!
