A couple of items for your consideration:
With the move 'Grovel' it would be much more appropriate, if the affect character held the pose for longer, ie until the start of their next turn or until attacked by another foe etc. (Don't know if you want any additional penalties at higher levels?)
Minor bug, the septum piercing on a character (large picture in gear 'tab') disappears when a simple ball gag is equipped. (Don't know if other gags are similarly effected)
