My evil is as subtle as a panther’s breath. I will dwell in darkness for a time, stealing the shadows of the righteous and powerful. That they begin weaker is no difference to me. They will serve me eternally, and I will resurrect them again and again, until the wicked deeds of their shadows outlive the memory of even their greatest legends. I will wed them to demons and sidhe, and the righteous will birth and raise their own destruction.

TL;DR - capture elite shadows. Breed them to powerful minions with Brood. Train them with Promotion, and use them endlessly with Joining and Recycling.
