An Ellectrose overload is a Shiira defensive weapon system.
this system uses an Ellectrose core crystal as power source.
By overloading the core crystal's energy, the crystal will generate a massive blast, causing an powerful EMP wave.
However using this will mean that all core crystals on the ship will be out of commision as well, the crystal that was used will also need a tech specialist in order to be repaired.
needless to say, the range of this weapon is limited to the amount of core crystals in the ship, but is general an close range last resort tyoe of move.
