DSM's list is great, all of those items are fantastic for a mage. I'll add a few more things.
https://wiki.project1999.com/The_Mystic_Cloak - Easy quest to do, also an interesting utility item to have.
https://wiki.project1999.com/Regal_B...Bathezid_Quest - Just the first ring is pretty easy to get, and not bad at all.
https://wiki.project1999.com/Tarton%27s_Wheel - It's a wizard quest, but the Star of Eyes is a cool item, you can also use it as a GCD refresher.
https://wiki.project1999.com/Aid_the_Dar_Brood - Nice non robe chest/back item, super easy to do if your guild kills Zlandi
I'd also add that having a Velious city armor bracer/boot/robe is also handy. All of those clickies have their uses.
