The Ishtar Edge is similar to the Over Weapon, it alters the energy levels of conventional weapons by utilizing the power of the CRAW. The twist is that the weapons themselves are coated with nanomacine, both to protect them from enemy weapons and the destroy objects with which they come into contact. The Ishtar Edge can also activate proton explosions within the layer of nanomacine to boost the convention weapons' power and range.
Both the Over Weapon and Ishtar Edge are technically in the experimental stage, since the control system of the nanomacine and its proton explosions is frequently unreliable, but the onset of the First Annihilation forced them into use before the testing process could be completed.
