Changeling
Humanoid (shapechanger)
• Medium size
• 30’ movement
• Standard Vision
• +2 Racial Bonus to one ability score: Changeling characters get a +2 Racial bonus to one ability score of their choice, this ability score bonus can be shifted to another ability over the course an uninterrupted hour of internal manipulation. If applied to intelligence, this bonus functions as a temporary bonus and does not grant additional skillpoints.
• +2 Racial bonus on saves vs. Sleep and Charm effects
• 'Linguistics’ is always in-class.
• +2 Racial bonus on Bluff, Intimidate, and Sense Motive checks.
• Changeling characters gain a bonus feat for which they must meet the prerequisites. At the beginning of each day, after resting, they can choose to change the bonus feat to any other feat for which they meet the prerequisites. This bonus feat cannot be used to meet feat or class prerequisites.
• Minor Change Shape (Su) – Alter Self at will as a Full Round Action. This is a Transformation, not an Illusion. The Changeling’s body changes, but not its possessions. The change is permanent until willingly changed. Use of this ability grants a +10 Circumstance bonus on Disguise checks.
You can assume the form of any Small or Medium creature of the humanoid type. If the form you assume has any of the following abilities, you gain the listed ability: swim 30 feet, darkvision 60 feet, low-light vision, and/or scent.
Small creature: If the form you take is that of a Small humanoid, you gain a +2 enhancement bonus to your Dexterity.
Medium creature: If the form you take is that of a Medium humanoid, you gain a +2 enhancement bonus to your Strength. Use of this ability grants a +10 Circumstance bonus on Disguise checks.
Overall, compared them to a half elf… They get a feat they can change up which is better than a skill focus 1/day, yet don't have multi-talented. They get +2 to any ability like the half-elves (though with a lower powered int version), skill bonuses are roughly the same, and gain alter self for low light vision, elf blood, and a lower powered sleep/charm save bonus.
Anyway, based this off a post I saw, hope it works, I'm a little iffy on the alter self, but disguise self always seem too minor of an ability and this gives changelings the versatile feel.
