Animate Dead Buff Ability Pathfinder

[kirerellim]

There is a passive ability somewhere that increases the controllable amount of undead through Animate Dead. I think it makes it so you can control 2hd more per caster level, though I'm not sure. Its not Undead Master. I thought it was a class ability, but now I'm not finding it and its making me crazy! Anyone have any idea what it is?

EDIT: ... I'm an idiot. It was the prestige class I was planning to build into, Agent of the Grave. ><

Don't forget the use of Desecrate before animating.
