Psionic characters manifest powers, which involve the direct manipulation of personal mental energy. These manipulations require natural talent and personal meditation. A psionic character's level limits the number of power points available to manifest powers. A psionic character's relevant high score might allow him to gain extra power points. He can manifest the same power more than once, but each manifestation subtracts power points from his daily limit. Manifesting a power is an arduous mental task. To do so, a psionic character must have a key ability score of at least 10 + the power's level.
Daily Power Point Acquisition: To regain used daily power points, a psionic character must have a clear mind. To clear his mind, he must first sleep for 8 hours. The character does not have to slumber for every minute of the time, but he must refrain from movement, combat, manifesting powers, skill use, conversation, or any other demanding physical or mental task during the rest period. If his rest is interrupted, each interruption adds 1 hour to the total amount of time he has to rest to clear his mind, and he must have at least 1 hour of rest immediately prior to regaining lost power points. If the character does not need to sleep for some reason, he still must have 8 hours of restful calm before regaining power points.
Recent Manifesting Limit/Rest Interruptions: If a psionic character has manifested powers recently, the drain on his resources reduces his capacity to regain power points. When he regains power points for the coming day, all power points he has used within the last 8 hours count against his daily limit.
Peaceful Environment: To regain power points, a psionic character must have enough peace, quiet, and comfort to allow for proper concentration. The psionic character's surroundings need not be luxurious, but they must be free from overt distractions, such as combat raging nearby or other loud noises. Exposure to inclement weather prevents the necessary concentration, as does any injury or failed saving throw the character might incur while concentrating on regaining power points.
Regaining Power Points: Once the character has rested in a suitable environment, it takes only an act of concentration spanning 1 full round to regain all power points of the psionic character's daily limit.
Death and Power Points: If a character dies, all daily power points stored in his mind are wiped away. A potent effect (such as reality revision) can recover the lost power points when it recovers the character.
