Using Emotional Grip following Moodlight Blinding gives a special result ("use opponent's blindness"), but seems to be same base damage, which especially makes me wonder if there is something hidden there. There are not a lot of opponents that block stealth attacks but using it against the Stained Glass Messenger gives:
You use the glass figure's blindness to maneuver in and grab it for 15 stealth damage, but its fragmentary barrier blocks all but 7 damage.
Fragments of stained glass manifest around the glass figure.
No Undodgeableness from that, though it's possible that the Glass Helm the messenger uses is Non-Undodgeable. Needs investigation.
