If you do not have at least a zero score in a Discipline, you may not employ powers that involve it.

Powers:

Psionic powers don't have a set level, but rather can be employed at whatever level is necessary. The actual level required is equal to the difficulty of the task

Psionicist Character Creation

Some Psionic Virtues & Flaws:

+2: Enduring. You have a particularly enduring constitution, and have one extra winded fatigue level. This virtue may be taken more than once.

+2: Limited Discipline Access. You have limited access to one of the Disciplines, and start with a zero score. You can learn powers within it, but not employ spontaneous effects.

+3: Discipline Access. You have a zero score in one of the Disciplines, and have the potential to both learn powers within it, and invent spontaneous effects.

+4: Creative Psionics. While you are competent with the common powers, you find their set forms stiltifying. [hi. i need a system.]

-2: Self-taught Psionics. You have learned to tap the powers of your mind on your own. You may not start out with any of the standard powers, though you may employ spontaneous effects normally.
