The Return of Ishtar/Portcullis


 * Ki and Gil will enter this room through the door at the top-left of it. It contains two Druids, one Wizard, eleven Golden Hyper Knights, five Dark Green Oozes (which take 1039 hits to kill) and one Land Urchin (which can immediately invalidate Gil's energy fraction on contact so try not to let it happen)
 * The key at the top-left of the room opens that aforementioned door at the top-left of the room, and the key at the bottom-right of the room opens that door at the bottom-right of the room. That aforementioned door at the top-left of the room leads back to Waiting Room (Room Pass: 9V7, it same as Alchemist's Room) - and that door at the bottom-right of the room leads to Entrant Hall (Room Pass: D37 - same as Dormitory). Remember the 2nd.
