I'd suggest putting a cap on the Augment damage of the Psionic version- We don't want any Psions dumping all of their PP into it- the result could be rolling hundreds or even thousands of Dice for it in the case of Epic Psionicists. @_o
Even worse if they dump all their points but a few then cast Permanence on it.... Then figure out some way to tow it around. Gah.
There is a cap on it. Psionicists can't spend more power points than their manifester level.
I laugh at myself first, before anyone else can.
