Invisibility to Mental Sense group

[OddHat]

Does Invisibility to the mental sense group protect against the effects of Mind Scan or Tellepathy? Or does it only protect against enhanced senses defined as mental senses?

I.E. Tommy Psion wants to be undetectable to mind scan. Is Invisible to Mental Senses the way to go, or should he just purcase a huge chunk of mental defense, only vs. mind scan?

It hides the character from Mental Group senses. That includes Mind Scan (see 5E 105). It generally doesn't matter against Telepathy, since that requires LOS -- if the mentalist can see you, he can use his Telepathy on you, since Telepathy isn't a Mental Sense Group sense (even though it has sense-like aspects).
