Some skills and abilities are limited to certain species, either as a result of biology, culture or upbringing. Only members of that specific species can purchase these skills.

Ascendancy Terrans have access to highly specialised mental training that focuses their will and allows them to perform astonishing feats of resilience and fortitude. Ascendancy Terrans may purchase the Discipline Skill with their character points, and the skills that use it as a prerequisite.

N-DAX, or Non-Differentiated Avimorph Xenoforms, are prone to genetic shifts which cause them to manifest powerful physical characteristics. These Mutation Skills can be acquired to grant an N-DAX character enhancements to their basic species abilities, but require them to adopt additional Species Trappings as they increase in rank.

Notumi Corpori control symbiotic nanite swarms linked to their notum-infused brains. They link to those swarms using a specialised device known as a Nanodeck, which can perform a wide array of functions, called Programs. A Program is more than simple lines of computer code - it is an intimate dance between the users thoughts, the Nanodeck's software, and the configurations of their nanite swarm. All Corpori start with knowledge of 2 Basic Programs and 1 Advanced Program, and can buy additional Programs with the following skill. To see the full list of commonly available Programs, see the Nanodeck page.

Tulaki are universally brought up within the faith of the Dominion, the Path of Tulak. Their religion teaches that individuals can obtain immortality as spirits upon their death by striving for ultimate accomplishment within their chosen field, usually under the patronage of a specific Immortal Spirit. Those who dedicate themselves to this task are called Heroes, and are often afforded great respect and status in Dominion society. Some adherents, however, forsake the quest for immortality and choose instead to guide others to greatness - these are the Priests of the Path. The Ecclesiocracy of the Dominion teaches the arts of stirring rhetoric, and the use of strange devices and mysterious chemicals that are thought to be able to interact directly with the spirits. Priests use their abilities to bridge the worlds of the spirit and the material. The skills that allow characters to become Priests and Heroes are called Devotions. Devotions are ranked skills, and cost 2 character points per rank (which does not increase with multiple purchased ranks).
