You just watch X-Men 3 or something?
Targets of psionic attacks will get a "saving throw" against their will to resist the attack. In order to protect against psionic attacks it would have to be determined how they work. That's a project of the T.F., but I would save that they haven't determined it yet.
Will? Wouldn't that only be for egokinesis? The rest would be endurance..
All psionics should work against Will, IMO, since all psionics are based on Will. A character's strength in psionics other than ego aren't based on something other than Will, so why should saves be? You can say that all psionic attacks are against the brain and the brain causes the body to be effected based on the power used.
Psionic attacks that are against the brain should be saved against will. Gravikinesis creates physical effects, so will based saves don't make sense there.
What I think should be the case is that psionic attacks can be saved with Will and with a secondary attribute (except for egokinesis), so gravikinesis would have strength based saves along with will based saves.
The will based saves should only be available to other psions though, and count as an almost 'counter spell' style thing, where they pit their psionic power in opposition to yours, battle of wills style.
