In 0.0f, the Starene Bomb was replaced with the Brimstone Bomb.===
Starene Bomb is a Formation made out of two square pyramids and a cube. It can be only constructed from Starene. As of version 0.01b, formations can be placed on any surface, even ones you've placed yourself. This makes it possible to explode anything but the base unbreakable substance.
Upon completion, the Starene Bomb will blow up after about two seconds, breaking some of the Substance it is connected to. You can only build one at a time and starting a new one before the last one detonates will stop the Formation from being recognized.
As of version 0.01a, the Starene Bomb is unique in that it is the only way to break currently unbreakable materials.
