Spell of Oblivion

Spell of Oblivion (망각의 주술, Mang-gag-ui jusul) is a spell placed on the Hidden Floor.

A Disciple of Workshop has used this spell to protect the knowledge of the Hidden Floor, in case those who have stored data of themselves in the mirror on the Hidden Floor try to reveal anything about it's existence to the outside world, in turn they will forget everything about the Hidden Floor.
