mentally posses others ?

[St. Evil]

When a Mind Mage uses this power is there a save? In the psionic powers section for saving throws against psionic attacks, it does not list this power. Then I looked into possession and it states not to be confused w/ the psionic power. As a GM I want to be fair and a clarification would be appreciated.

Saving throw is standard, unless there's no life-force inhabiting the living body you target (i.e., they're astrally projecting or possessing somebody else or something).
