What does every combat mage need?

[Deftninja]

I tend to play only Arco, and I set my mages up with eye of aiming, pendant of luck, robe of shadows, and boots of the messenger.

I'm not sure how well the robe of shadows really works, but I still tend to lose some mages in combat from flyer attacks and missile barrages.

How do you equip your combat mages?
