Delit is a weapon designed specifically for Evelyn. It works on the principle of 'dividing by zero', which, essentially, means that it manipulates the very fabric of spacetime and causes discord and destruction. The weapon's exact power, range, and accuracy are unknown, as only Evelyn is capable of firing the weapon. The outer casing appears to be made of one piece, and it is impossible to disassemble the weapon without destroying it.
It is assumed that Delit has multiple effects, but these are all based on its user, and cannot be tested.
