"Randomly adjusts its flight vector for more coverage."
The Quantum Variegator is a long-range weapon that rapidly fires pink projectiles as long as the attack button is held. The projectiles will randomly adjust their path in flight and do not seek targets, making the weapon somewhat difficult to aim. There can be a maximum of 8 on screen at a time.
The Quantum Variegator weapon can be found in the middle-left portion of the lower-middle large room in E-Kur-Mah. After fully exploring the room, this will be the last empty square on the map. A Passcode is required to gain access to this weapon. The Passcode is obtained by corrupting a Hopping Shrubback found in this room.
