Alas, I've started the quest line but haven't found Millie yet. I've been told (but have not verified... /me shuffles through her stickie notes)...
This is the egg harvesting step, right?
Activate the clockwork owlbear when you are near a female owlbear. You will turn into a clockwork owlbear so be sure you are in a safe spot! Run over to the female and target her. Remember you will need to get the egg afterwards, so pick a female towards the edge of the group.
One by one, use abilities 1 through 4. If she does not drop the egg then, repeat. Once she has dropped the egg she will become an NPC and will move away immediately. Use ability #5 to dismiss the clockwork owlbear and resume your normal perspective. The egg will then be harvestable.
That's the end of the notes I have. I repeat, I ahven't verified this yet.
