I'm a Resto/Elemental Shaman. I like shields. I especially like Epic shields. I especially like Epic shields with spell damage on them. And boy do I like Epics that have a nice tie to the lore.

Name: Antonidas' Aegis of Rapt Concentration
Type: Epic Shield
Armor/Block: 6336 / 174
Abilities:

• +28 Stamina, +20 Intellect
• Improves spell crit rating by 20, and increases spell damage and healing by up to 42
• Antonidas is (actually was, because he was killed by Arthas, as all great Warcraft characters were) the head of the Kirin Tor, that conclave of wizards that you're hearing so much about lately. His pupil was Jaina Proudmoore (and it was she who he expected to eventually take over the Kirin Tor). When Arthas killed Antonidas (to claim the Book of Medivh), the Violet Citadel and Dalaran were both left wide open, and Archimonde moved in to finish off the job and destroy the city.
• Now, of course, Dalaran is being rebuilt, and it's soon going to be flying over Northrend. Until then, Antonidas' shield has found its way back into the hands of players.

How to Get It: In fact, Archimonde must have grabbed it when he trashed Dalaran, because this is a drop from him at the Caverns of Time Mount Hyjal instance. In that instance, you fight Archi (as I like call him) fighting to gain control of the World Tree, and apparently he's been hauling this shield around with him ever since he sacked Dalaran-- drop him, and with a little rolling luck, it's yours.

As a sidenote, apparently this was one of the drops on the world first kill of Archi as well. So not only can you get a shield that belonged to one of the greatest arch-mages the world of Azeroth has ever known, you can also get a shield that belonged to one of the best guilds in the game! Two for one!

Getting Rid of It: Sells for 9g 55s 99c. Disenchants into a Void Crystal. Breaks my elemental Shaman heart.
