Enlightenment of a SP Addict

Oh you're kidding. Wraith Lords can cast a drain life damage shield? That's just disturbing.

My Wraith Lords typically run around with wraith swords, chainmail of displacement, spirit helm, boots of flying, amulet of antimagic and pendant of luck. Their mission is set to Attack Rear. Should I script it cast Soul Vortex, Attack Closest Enemy instead? I could probably eat a whole lot of regular troops that way.
