Notes from author
Remember those bastards in the catacombs? Well now you too can command armies of the dead to defeat your foes! Cast Undead Rapport to recruit a team of hollows, use alluring skulls to lead them around, and set up ambushes for unwitting invaders. Becomes much more effective in higher NG+ levels.
Optional: You could equip a catalyst and use aural decoy in place of alluring skulls, but then you wouldn't have the necromancer's signature fireballs and you wouldn't be directing your army of the dead by flinging skulls around. Seriously, what kind of necromancer are you?
Unlisted: Equip a skull lantern. Real necromancers use skull lanterns.
