Special Weapon Effects

Fun detected. Obliterate. – Increased weapon damage. Consumes 6 ammo per shot. Has a weapon charge-up time and fires a highly accurate laser.

Usage & Description

The ION CANNON is capable of one of the highest single-shot damage outputs in the game when fully charged. This, along with its pinpoint accuracy, means that this weapon can reliably kill most mob-type enemies in one to two hits, and can be used for sniping during Fight For Your Life. A short charge will increase the ION CANNON's damage by a decent amount, and a full charge takes a relatively short amount of time. The ION CANNON's heavy ammo consumption means that it should be reserved for emergencies or for boss fights.

The ION CANNON pairs very well with any character, but especially so with Moze, due to skills like Forge allowing for ammo regeneration, and a majority of her Demolition Woman skill tree buffing splash damage output, especially Torgue Cross-Promotion.

The ION CANNON notably synergizes with abilities that use overkill damage. The Enforcer Guardian Rank reward Overkill allows any other gun to become capable of one-shotting regular enemies after a kill, while Amara's Remnant will add overkill damage to her homing orb upon killing an enemy.

The ION CANNON can also be extremely effective with the "Gain 300% increased Weapon Damage against enemies above 90% health." anointment, allowing the weapon to one-shot nearly any basic enemy, and even many bosses given the right setup. However, note that if this anointment spawns on an Ion Cannon that fires two lasers per shot, it will only apply to a single laser, meaning that it's much more effective on Ion Cannons that fire one laser.
