I see nothing unrewarding about the ability to move over terrain. But perhaps a simple passive bonus, such as bonus damage on your attacks to sweeten the pot. ;)

If you're over terrain when you reduce to 0 Lift, clipping would *push* you out. Similar to if you target the middle of terrain with or ; or the reason why  fails. I'm fairly certain that I've seen have him standing in terrain while he's untargetable, and it just plops him down on one side.
