Question about the 'Necromancy' skill and 'Necro Call'

[Buzzrick]

I'm still confused about how the Necromancy Skill works, or whether it even actually works at all. I haven't seen any of my troops being resurrected after a battle even though I have level 2 in the skill. From the previous description I should be getting some of the dead troops back.

I don't get any feedback that there were troops revived, and my troop numbers stay at the same reduced number after a battle.

I'm running the GamersGate downloadable version with the GamersGate patch. In the game it reports to being version 1.6.5
