Are there any manuals either in Core or 3rd Party that feature feats for racial subraces (aka Svetocher, Wildborn, Rainkin, Angelkin, Beastbrood, etc etc)?
In the ARG some racial feats require specific alternate traits. Closest I could think of.
ARG?
Advanced Race Guide, on the PFSRD. I really should stop using acronyms... Pathfinder System Reference Document.
