Good catches! I found a few other problems: "psionics" rather than "psi-like abilities", spell resistance rather than power resistance...
Updated.
Yeah, let's finish up the non-psionic standard opinicus before continuing with the greater version.
Updated Opinicus.
Added Greater Opinicus.
We'll need additional skills, feats, and spells.
Do we want to improve the sun sparkles damage?
Hold on, the regular opinicus has "Special Attacks: Improved grab, rake 1d4" but its Combat entry has "Rake (Ex): Attack bonus +7 melee, damage 1d6+1". Better drop the +1 and make both damage dice match.
How about increasing its sun sparkes by 50%? "All evil creatures within 30 feet that meet its gaze take 4d8 points of damage (6d6 for an evil outsider) and become blinded for 1d2 round."
Hold on, I've just realized I'd proposed giving the Non-Psionic Opinicus sanctuary 3/day when it already has sanctuary as a cleric spell at a higher DC. Do we want to change that SLA to a different low-level defensive spell, such as blur or mirror image?
Mirror image sounds pretty good for these.
