This is house rules stuff for those who enjoy playing with psionics. The way I see it, everyone has a mind, an id, an ego, and a psyche, therefore everyone is potentially vulnerable to these psionic attacks (not just Psionic Blast, as defined in the 1e rules). Giving psionics the ability to attack non-psionics is potentially a big "game unbalancer", so I am trying to constrain these powers to logical limits while still keeping them somewhat effective and fun.
The PH1e states that Psionic Blast is costly in terms of attack point expenditure, but is the only attack that can affect non-psionics. I take that as a statement of intended game balance, and I respect the logic of it. I would postulate that any psionic attack used on a non-psionic costs 20 extra strength points. Keep in mind, the psionic must have a current psionic strength of at least 100 to be able to affect a non-psionic. Thus, only a very powerful psionic would have a chance at using their powers on a non-psionic.
Used on a non-psionic, the Mind Thrust would cost 24 points. The attack range of the Mind Thrust is as follows: Short - 3", Medium - 6", Long - 9"
The Mind Thrust is a stabbing attack which seeks to short the synapses of the victim. I think of it like swirling a stick inside someone's skull. You are basically just trying to mess something up. When used on a fellow psionic, the Mind Thrust can wound or permanently damage the victim's psionic abilities. When used on a non-psionic, I figure that worst case scenario, it can cause the loss of INT or WIS points.
