Sfer Cubes are, as the name suggests, cube-shaped blocks of Sfer.
In Recollection: Collapse, Sfer Cubes are used to fix the disabled Movefriend.
Sfer Cubes can be gained from clearing out Recreation, the Personnel Tendril, killing all the Hostile Containers in Kazki's Room and by visiting Miltza's Room.
