The Sphinx is actually a living statue. I understand that if you finish the animation, it will become fully mobile. Then, necromancers kill the creature :D and resurrect it again as undead. Otherwise, it wouldn't be very fitting to have a living sphinx in the undead ranks :D. It's a really interesting unit, and I hope it will be a champion. Although, I didn't have any complaints about bone dragons. In "Heroes 5," I really liked how they disintegrated. But I didn't really like the spectral dragons. By the way, it turns out that the sphinx is the same as a bone dragon, only with a human head (skull).
