The Return of Ishtar/Goblin's Lair


 * Ki and Gil will enter this room through the door at the centre of it. It contains one Orange Bat (ten hits to kill), one Blue Bat (twenty-six hits to kill), one Green Ooze (eighteen hits), two Black Oozes (ninety-six hits), one Blue Snake (twenty-eight hits to kill) and one Orange Snake (seventy-two hits kill).
 * The second key at the bottom-left of the room opens the door at the top-centre-right of the room, that second key at the centre-left of the room opens the second door at the top-right of the room, the first key at the top-centre-right of the room opens the second door at the top-left of the room, and the first key at the top-right of the room opens the aforementioned door at the centre of the room. The first key at the bottom-left of the room, the first key at the centre-left of the room, the second key up at the top-centre-right of the room, and that second key at the top-right of the room do not open any of the doors in the room, which means there are no keys for the first door at the top-left of the room, the door at the bottom-centre-left of the room, or the first door at the top-right of the room - and there is no way of knowing which rooms they lead to until you are led back here through one of them...
 * The door at the top-centre-right of the room leads to Thief's Hideout (Room Pass: 7V2) - while that second door up at the top-right of the room leads to Forgotten Room (Room Pass: 737), the second door at top-left of the room leads to Trap Door Room (Room Pass: SF7), and the aforementioned door at the centre of the room leads back to Specter Cell (Room Pass: QFY). You should remember the first, second and third of these Room Passes, as the last one is of little use to you.
