Human Alternate Racial Traits

Bonus Feat: Gain one extra feat at 1st level. Replaces Elemental Lineage.
As they can be found in each and every corner of the world thanks to their burning curiosity and varied natures, many humans are born with inherently more potential than others - a sign of their extraordinary lineage or past.

Ssarin Pureblood: Gain Detect-Poison as an at-will ability as per the spell. Gain a +2 to your natural armor bonus and as a standard action that provokes Attacks of Opportunity, you can change into or out of a Viper Form, turning into a mundane viper snake. This functions as Beast Shape I, and is an extraordinary ability. Replaces Elemental Lineage.
Though their numbers have been dwindling rapidly ever since the fall of the Tyrant Cao Lu and the subsequent redemption of the Lamia God-Queen as their creation was deemed immoral and outlawed, the Ssarin Purebloods are those humans who trace their roots back to the High Lamia who served the Tyrant Cao-Lu, whose ancestors were living experiments designed to create a more useful servitor race for the ancient Lamia. Though many now seek better lives, most still reject the ways of civilization and live alongside their more snake-like kin deep in the world's jungles.

Focused Study: At 1st, 8th, and 16th level, you gain Skill Focus in a skill of your choice as a bonus feat. Replaces Skilled.
Though all humans are skilled, some are less generalistic and more specialized in their studies.

Specialist: Gain any two skills as class skills and gain a racial +2 to them. You may switch one skill with a mental attribute to a physical one, or vice versa. Replaces Skilled.
Though all humans are skilled, some are so specific in their studies they learn of new ways to use their knowledge and technique.

Faded Lineage: If you have the Arcane bloodline treat their Charisma score as 2 points higher for all sorcerer spells and class abilities, and you use all domain spell and powers of the Knowledge and Magic Domains at +1 caster level. Replaces Elemental Lineage.
With closer ties to the humans of the ancient Aurelian Empire than the Spirit Kings, these Humans have vestiges of the incredibly arcane power their ancestors once wielded burning in their veins.

Vestige of a Wish: Gain a +2 on all saves versus spells or effects from the Necromancy school. You count as 2x your HD for the purposes of being raised as an undead. Replaces Elemental Lineage.
Though the memory of their ancestors and their struggles has faded into myth and legend, Humans remain oddly resistant to being raised even long after they have died. Though not outright immune like their ancestors, those who raise the dead find them a bit harder to control than other species.

Ssarin Biology: You gain a +4 on saves vs diseases and poisons. You gain scent out to 30ft(or +20ft to existing scent). Each time you reach the next age category for your race, you roll a 1d100 - if the result of the die is greater than (50 - HD), you gain 1d10 more years in the current age category. Replaces Sixth Sense.
With bodies made supernaturally efficient by the meddling of the Immortal Emperor Cao Lu in the bloodlines of their Ancestors so long ago, these descendents of the servants of Cao Lu find their bodies capable of living longer than normal, resisting diseases and poisons, and often find themselves developing forked snake-tongues to sniff the air with.
