(General)
Your dual heritage makes you something more than merely a mix of your parent races.
Prerequisites
Two subtypes,
Elf blood or
Orc blood racial trait.
Benefit
For the purposes of any effect related to subtype (such as a
Ranger's favored enemy and bane weapons), you count as neither of your subtypes, and you no longer count as either of your parent races for the purposes of effects related to race.
