I just finished doing a compilation of mind's eye stuff and didn't see it, and I'm positive it's not in the Psi HB.
It's only 1 to the DC's, and as my current projection for psionic DC's hits 52, 53 isn't going to matter much against average high 20th level saves of +25 (much less against low saves of +15).
But still curious, one more point makes it feel that much more complete.
Telepath, Seer, or Shaper 6/Shadow Mind (Mind's Eye)9/Arch Psion (Mind's Eye)5.

INT, WIS, or CHA = 18 (base) +5 (levels) +5 (tome) +6 (headband, periapt, or cloak)= 34 +2 (psionics prodigy) +16 (3x Overpowered Animal Afinity)= 52 INT, WIS, or CHA
(52-10)/2= +21 to DC +4 (Subpsionics) +2 (Psionic Focus) +6 (Greater Psionic Focus--High Psionics) +1 (Psionatrix of Telepathy, Clairsentience, or Metacreativity) +10 (base, or average d20 roll) = 45 - 53 for 0-9 level powers.
Not a submission, just playing around with Mind's Eye stuff.
Throw in a Torc of Psionic Might from the vanilla Psionics Handbook and he can metapsionic stuff up to a cost (normally) of 22 PP (Transcend Limits = Level +1 = 21 + Torc -1 to cost = [effective] 22). That'll let you get off say a Fortified Double Overpowered Mass Concussion (assuming Telekinesis was one of your secondary disciplines). 7d4 doing 17 damage average + 17 for each overpower and + 4 for the fortify is 55 points of damage no save. Actually, that's rather sad for such expediture. Poor psions.
Maybe if instead of the third psionic focus feat you took a second transcend limts feat... Then you could maximize a detonate for 102 points of damage or overpower it for an average 119 points of damage. Sheez. Psions got shafted when it comes to damage.
Hmmm.. Maybe if you used fission to divide then both you and your copy did twinned maximized mass concussions.. Nah, too expensive, and still low. Oh well. Back to cleric archers and shield bashing paladins.
**Edit: Oops. And technically, that's not even a legal build. I'm so used to our house psion I forgot. Psions don't get bonus feats at 5, 10, etc. We scrapped psionic combat and gave bonus feats instead.
