I'm loving the class so far, though I'm itching to see those blank spots filled. I have a couple ideas off the top of my head to kill those empty levels. A class feature that grants mind-breaking or petrifying gaze attacks to go with the eye features would add to the 'nameless horror' theme of the class. Who doesn't like eye beams?
Maybe at higher levels the Ozodrin get the ability to 'project' a feature like an eye or tentacle onto a specific type of nearby surface to restrict enemy movement (fill a space with tentacles to make it count as rough terrain/impassible) or scout (put an eye on the opposite side of a door). Though the Lure Trap seems close enough to this and much more flavorful, it's just a thought.
