Ok, I'm pretty sure this is just a dumb, but hopeful, question. Is there any chance that they Erattaed Steep Hill so that it can work with conjurations that attack (i.e., temple of light, akiro's hammer, Ballista---which I just saw in Lost Grimlore)?
Because it would be so cool to put akiro's hammer or a temple of light on a giant hill....especially since one of those gets completely Shut down by incorporeal walls....
