Call of the Wild - For just 15N gems you get a werewolf thug + 20 wolves if cast in a forest. The werewolf can summon allies as well 2 or 3 more wolves per turn.

Awaken Sleeper - The firbolg does it all, good leader, good melee thug, good sharp shooter, keeps the morale of your army up. 10N gems, a steal.

Black Servant - Etheral/stealthy/life drain, what more do you want for 5D gems? Equip with quickness/skull talisman or skullface to get a 1 man army stealthy raider.
