A Psychic Seeker simply knows their powers; they are ingrained in the Seeker's mind. They do not need to prepare their powers (in the way that some spellcasters prepare their spells), though the Seeker must get a good night's sleep each day to regain all their spent power points. The saving throw DC against Psychic Seeker powers is (10 + the power's level + the Psychic Seeker's Intelligence modifier).
