I'd like the ilari to give you a couple healing potions to go along with those warp potions they give, personally. Not too many, just 2 or 3.
I also agree that these buildings need more of a point. How about extending them forward into the third dimension creating a barrier with an entrance/exit on either side so that you have to go through some buildings to proceed along the level (unless, of course, you have bat/teleport/it's low enough to ride some lightning over)?
