Magnetic Warhead

Magnetic Warheads can be summed up as an offensive variant of Magnetic Shield that capitalizes on the fact that unstable and damaged shield of this type can literally tear the ship apart with its magnetic field currents. The magnetic warhead is an archeotech that is supposed to do that on purpose to other ships.
The moment it reaches the target, it 'explodes', generating massive (and completely random) magnetic fields, with enough power to bend ships into space equivalent of pretzels, if the hit is direct. But even glancing hits cause A LOT of damage. It's one of those rare types of warheads that actually ignores armour almost completely, making it especially useful against heavier ships.
Unfortunately, it is rare. About as much as an average archeotech, but it still makes firing entire salvoes of those a dream. But if one of them manages to be the one to reach the enemy... the effects are generally pretty spectacular.
