Fiendish feats are a type of Heritage feat which is available to those with a fiendish ancestor. To take a fiendish feat, you must possess the Planar Bloodline feat for the Demon Bloodline or Devil Bloodline, possess the Demon or Devil bloodline through another means, be a member of a race descended from fiends, or have a class feature specifically granting you access to Fiendish Feats.
As a type of Heritage Feat, any creature with the Outsider type who also is classified as a Demon or Devil or who has the (Evil) subtype may select these feats as though they possessed the Planar Bloodline feat and a number of bloodline levels equal to their racial Hit Dice. (This does not actually grant them an ancestral bloodline.) They must meet all other prerequisites before selecting a feat.
Possessing Fiendish Feats is itself an act of Evil. If your alignment is not already Evil, choosing to gain a fiendish feat moves your alignment in that direction.
