Ki and Gil will enter this room through that sole door at the top-left of it. It contains two Druids (which take five hits to kill), two Wizards (which also take five hits to kill), two Golden Mirror Knights (which take total of 175 hits to kill) and three Dark Green Slimes (which take total of 208 hits to kill).
The Treasure Chest in the wall's hole at the bottom-right of the room will restore the numerator of Gil's energy fraction back to 100, so don't miss it.
The soft-light hologrammatical image of Ishtar herself at the bottom-right of the room can be walked through by both Ki and Gil as if it was not there.
The key at the bottom-right of the room opens that aforementioned sole door at the top-left of the room. The keys at the left, centre-left, centre-right, right, bottom-left, bottom-centre-left, and bottom-centre-right will not open it. The sole door at top-left leads back to Goblin's Lair (Room Pass: DC2).
