As you enter the room, a cutscene will play, showing the release of several enemies. The first group consists of a trio of Pulsework Knights and the second has four Circuitrons. Be patient in these fights or you will find yourself in a mess. The adjacent room that follows will also release enemies - a Stikini and two Pulsework Knights. As always, focus on the Stikini first before it can cause too many problems.
Follow the path through the next door into a corridor where you can find a Feymark (weapon for Snow which increases Magic but lowers Physical damage) just to the right. Carry on through the next door to reach a new area.
