Yes, he does.

When using him for defensive purposes, don't take anything expensive. Usually, you just want to take a few choice gems and drop as much death as you can before he dies.

Now, the Lich pretender is VERY resilient and, especially deep in his dominion, can act as a good thug. Cheap equipment is very nice on him.

Master Lich is definitely a no-no... He dies from arrow volleys. Not that he can't wear stuff, just make sure he's got guards.
Phoenix can't wear anything anyway.
Vampire Queen? I think she moved to Mexico after Dominions 2...
Lich is built for thugging especially in deep dominion.
