The Celestial Tower and the Shadow Witch/Bonus
From Another Eden Wiki
Dogma Tower 100F Door[edit]
As you ascend the tower, you would have had to open several doors by rotating the dials until they form unbroken lines leading up to the center of the door. At 100F, you will find one such door which requires five dials to be set, but only one of the dials can be found on the floor. You will need to retrace your steps to the dials of the lower floors. Only the golden dials with four knobs on their edges will affect the door on 100F.
Once open, you will find two chests - one with three High Class Scroll, and another Stone Resistance Badge.
