Although no character in my group is Psionic, I was also looking through the Psionics section, and have a couple questions.
It seems that, as a character uses psionic talents, they use up their Psi. So if a character starts with PSI 9, and uses a talent that takes 1 point, they are now at PSI 8 and have gone from a +1 to 0 modifier (until it regens). Is this correct?
Also, I'm not sure about the point costs of some of the skills. For example, the Telekinesis power says it costs Strength + Range. What is Strength? It is confusing because the entire section refers to Psionic Strength as the PSI attribute, but this is obviously not that. It seems to be linked to how much (mass?) the character wants to move, but I'm not really sure. I don't remember seeing anything relating STR to carry/lift values, so I'm not sure how to calculate this.
