We were in a room with a rolling floor, with our end up a little higher than the rest, a few stair steps up if I remember correctly. The kid had us step up onto a low wall and the read the scroll. The entire room filled with dirt to up with the 'level' of the ground (wall) we stood upon. This buried all of the enemies in the room up to their neck in dirt, some were completely buried. Across the room, where once walls had stood suddenly open areas appeared as the dirt was magically transported away. This had some repercussions as the dirt/stone that once held the ceiling was now stripped away. The ceiling stretching out one acre in front of us suddenly came tumbling down (which also buried more of the bad guys after us that had been out in the hall and not yet inside the room). Luckily, another exit out of the room afforded us the opportunity to escape in a different direction, else we might have been trapped in the room.
Needless to say, a powerful spell if not carefully used. The spell could also be used to clear and level rolling hills for a nice clear camp site or good farmland. ;-)
