U4-Deceit-L5-Room-8

You enter on the west side and the corridor balloons to a larger, round room in the middle before narrowing back to a corridor at the east side. In the large center part of the room are nothing but sleep fields and two reapers, one at the north, and one at the south.

Unless you have a mage in your party who has benefited from all the Orbs encountered in the dungeon so far, you can expect to have your party members falling asleep quite regularly as you attempt to take out the reapers, who are casting Sleep auras themselves.

This area can be bypassed by casting Z, or Down, from the chest section of the main area of level 5, or Y, or Up, from the door section of level 6.
