Here's sort of a rough draft for an idea for a psionics system. I'm desperately trying to keep it very simple.

Race priority B as usual.

If someone is psionic, they practice their powers as proficiencies.

Focus =(MA + WP /2) average 4, + proficiency = (selected discipline) pool

Different skills (disciplines)= different proficiencies
Such as telekinesis, clairvoyance, telepathy, etc.

Options
PC's must choose whether their skills are of the physical or mental variety.
So a character may only have skills in effecting the physical realm, but could still have several skills. Example- a pc has the proficiencies of telekinesis at a pool of 6 and pyrokinesis at 5. Or they may only be allowed one skill period, depending on the game.

Meditation: successes can be reduced from TN, but don't allow spontaneous use of powers.

Certain "maneuvers" only available at certain skill levels
Activation costs for certain maneuvers
Target Numbers for certain maneuvers
No defaults

# of successes can have different results. Certain actions may require a certain # of successes. Using these skills does not deplete the pool or wear out the character.

Proficiency - Telekinesis
Base TN 6
must be able to see what he's doing
Factors
Distance 0-10 meters =0. 11-50 meters +1. 51-100 meters +2.
Mass 0-10 lbs =0. 11-50 lbs +1. 51-110 lbs +2.
Dexterity Point A to B =0. press buttons +1. Tie knot +2.
Speed 1-10 mph =0. 11-20 mph +1. 21-30 mph +2.
Modifiers are cumulative
No modifiers for use of powers when not under duress.

This is really just notes so far, but what do you think? Suggestions?

Seems interesting so far.. perhaps I might speak more when I see a finished product. I would go so far as to say that using the focus derived attribute might not be strong enough to wield cool and awesome results.
This can be hashed out in playtesting though.. and if it seems like it is too hard to accomplish.. add Kaa to Focus. I'm reasonably sure that perception should take a role in the equation also.

More thoughts on this later.

I've considered that. It seems like there should be more of the mental attributes involved, but when weilding the psionic skills as proficiencies, I didn't want to give a higher base #, because the character can still potentially develop his skill and power very highly. But yeah, this was just a beginning idea, and I'll be fleshing it out and testing it.
