Items with random effects

[Halcyon]

I've recently been making a wild mage, and hence looking for items with random effects for him to have fun with. The only three Ive managed to find so far (that aren't artifacts or epic items) are the bag of tricks, rod of wonder and the fist of emirikol. Any suggestions for other neat items with random effects?

If your DM is realllllllllllllllllllly generous, a deck of many things may help.

But you could always settle with a deck of illusions instead.

These items can be fairly random:
Amulet of the Planes
Chaos Diamond
Robe of Useful Items
Well of Many Worlds
