Ankh question?

[ColdSteel]

Okay, so I pay 80 death gems to forge the Ankh and equip it to a commander. The item guide says it provides life after death so I'm thinking if my commander takes a mortal wound, it's going to do somthing.

A bit later my commander dies in a battle, drops all his stuff to another commander, including the Ankh, and says 'bye-bye, see you at the pearly gates'. Nothing, nada, zilch. He's a deader.

So how exactly does the Ankh work and what exactly does it do? Do you have to be inside your own dominion for it to work, maybe?

Thanks.
