Psions are known for their hand-to-hand combat skills, usually derived from martial arts, and their intuitive capabilities enabling them to succeed against impossible odds. Surprise tactics are the best means to fight them, but their adaptive resilience means that they can evolve to counter even unpredictability.
Psions are said to be almost "psychic" due to their natural ability to predict their foe's actions before they even happen. As such, their augmentations are focused on calming their minds and sharpening their observation skills. Similar to Architects, they also carry equipment to help give information about their enemy's physical and mental state, so they can make combat predictions more accurately.
