Astrazoan Heritages
Sporting multiple personas adapted for multiple cultures, astrazoans are a dramatically diverse species despite their relatively low numbers.
Aquazoan
Source Galaxy Guide pg. 130
Astrazoans occupying aquatic worlds and communities learn how to integrate gills and fins into their forms and can even manifest these traits when imitating species that do not normally have them. You gain a swim Speed of 20 feet, and you gain the amphibious trait, enabling you to breathe in water and air.
Assimilated Astrazoan
Source Galaxy Guide pg. 130
Whether you were raised as a member of another species or became fully immersed in their cultures and traditions later, you have completely assimilated to another ancestry and feel as comfortable in that skin as in your natural form. Choose a common ancestry. You can select ancestry feats from the ancestry you chose, in addition to your character's own ancestry. You can select feats that require a physiological feature that you lack but can only benefit from those feats while you are in that ancestry's form; for example, an assimilated astrazoan who selects the shirren Basic Insectile Flight feat can only fly while in their shirren form.
Cloned Astrazoan
Source Galaxy Guide pg. 130
You were either born in a laboratory using genetic samples preserved from a distant ancestor or budded from a parent astrazoan. Your body stubbornly refuses additional external attempts to change you. If you roll a success on a saving throw against a curse, disease, or polymorph effect, you get a critical success instead.
Construct Copycat
Source Galaxy Guide pg. 130
You have reinforced your body with technological augmentations that can be shifted to give yourself the appearance of a constructed creature. You can use Change Shape to assume the appearance of a Small or Medium construct. You gain the Augmented Body general feat.
Wild Astrazoan
Source Galaxy Guide pg. 130
While most astrazoans flock to communities in densely populated settlements, some choose to live among nature in the wilderness, forging their own destiny or even defending their paradise from the influence of others. You have only one ancestry you can select for Change Shape, but you can also use Change Shape to transform into an animal with the statistics of a 1st-rank pest form.
Versatile Heritages
Borai
Source Player Core pg. 85
You've returned from the brink of death as a borai— at once both living and undead. You gain the borai and undead trait, in addition to the traits from your ancestry. Unlike other undead, you don't gain void healing. You're healed by vitality effects and damaged by void damage, as if you were a living creature. Likewise, you can be stabilized, healed, and brought back to life as if you were a living creature, save that you always return to life in your normal undead state (as a borai). You gain low-light vision, or you gain darkvision if your ancestry already has low-light vision. You can choose from borai feats and feats from your ancestry whenever you gain an ancestry feat.
Prismeni
Source Player Core pg. 89
You have an innate connection to the Drift. You gain the prismeni trait, in addition to the traits from your ancestry. While you're in the Drift, you can automatically pinpoint the location of Drift beacons, Drift lanes, Drift engines, and other Drift-related technology within a 100-mile radius. If you're Piloting a starship that doesn't have a Drift engine, you can serve as a connection between the Drift and that starship. This is a 1-minute activity that has the concentrate trait, and it allows the starship you're Piloting to enter or exit the Drift. Once within the Drift, the starship travels via conventional thrusters, as normal. When you get a critical failure on a Piloting check to Navigate or Plot Course through the Drift, you get a failure instead. You gain low-light vision, or you gain darkvision if your ancestry already has low-light vision. You can choose from prismeni feats and feats from your ancestry whenever you gain an ancestry feat.
