There's no shortage in destructive power delivered by technology. Yet, the same science of death can be further augmented, in some fields, by treading the sorcerous path of Destruction. It can be used to sharpen one's killing instincts, but the greatest power lies in directing the flow of energy: naturally-occurring energy of elements can be tapped and hurled towards enemies, or the energy of enemy attacks can be dissipated by enhanced armor (plasma energy will prove the most troublesome). We'll also need actual combat tech before we can enhance it.
