Rarefaction Cell

The Rarefaction Cell, or Energy Cell in the code, is a key item in 's campaign, found in Linear Systems Rail.



Function
It temporarily distorts gravity when used. Being heavier than many other items, the Cell cannot be swallowed and weighs  down slightly when held, resulting in a lower jump height, swim speed, and a gradual downwards slide when on poles or in tunnels while not moving. Pressing and holding Grab activates the Cell, distorting gravity for ~15 seconds and allowing for dramatically increased jump heights and swimming speed.

Bringing the Rarefaction Cell from The Rot to Submerged Superstructure is necessary for achieving the Old Friend ending. Being an important item, it appears on the minimap.

Trivia

 * According to and, Rarefaction Cells are the emergency power systems of Iterator superstructures, allowing them to keep functioning if conventional energy sources are lost or cease to work due to entropy and decay.
 * The Rarefaction Cells are also the main cause of the superstructures' gravitational anomalies, distorting space and gravity around them while active.
 * If they're lost or removed from a superstructure, the Iterator in question will slowly die.
 * Looks to the Moon lost her Rarefaction Cells when her superstructure collapsed, as they were washed away by the Shoreline's ocean.
 * Should the Rarefaction Cell be destroyed, e.g., through manipulating a, a slightly larger version of the effect will occur.
