White-haired (Witch) Archetype, not granting constrict special ability for feat Final Embrace requirement.
Following the defiler build on this hexcrafter magus guide: https://docs.google.com/document/d/1fSJuL1O4hs15NMk-y4MXbH9D_qt9V7iwhY2y9HDrs74/edit
And at lvl 5 it wants to add the feat final embrace. PCGen is saying I do not meet the requirements with:
Requirements: either ( either ( race: Naga at least 1, race: Serpentfolk at least 1 ), at least 1 Constrict Special Ability )
But, the constrict ability was granted on the white haired witch archetype (Dragon Empires Primer, p23), via the White Hair Constrict (EX) ability: "When your hair successfully grapples an opponent, it can begin constricting your victim as a free action, dealing damage equal to that of its attack."
