Making the Most of Level Drain

[Palanan]

In a very recent encounter from our Runelords campaign, half the party was hit with level drain from a necromantic free-for-all.

We barely pulled through, and now I'm wondering if there are any potential advantages to having recovered from the experience. In 3.5 there's the Hunter of the Dead, a PrC from Complete Warrior, which has exactly this situation as a prerequisite. Is there anything similar in Pathfinder?

None that I'm aware of in 1st party material (http://www.d20pfsrd.com/classes/prestige-classes). There might be something in 3rd party (http://www.d20pfsrd.com/classes/3rd-party-prestige-classes)?

Unfortunately, I'm not too familiar with 3rd party stuff. Sorry!
