P6 or P8 and 3PP

[ShadowcatX]

I was wondering for P6 or P8 if there are any 3PP specifically designed for them? If not are there any you feel might have special relevance in that style of campaign?

P6 and P8 are play styles where characters cannot go above the listed level and instead continue to gain feats rather than levels after achieving max level.

The only thing I know is Storm Bunny's Bloodlines and Black magic which uses their Occult7 hack, but it's a complete cleaning up and rebalancing for modern urban fantasy with PF basis.
