Splitter lasers are like Laser Shotguns. They fire multiple laser bolts at the cost of three laser ammo per shot. Their projectile velocity is moderate, able to easily hit short-range targets, though they do require the user to lead the target at longer ranges.
Depending on the manufacturer of the laser's body, the Beam lasers can spawn with manufacturer-specific gimmicks:
Dahl Splitters fire in bursts when zoomed in and have reduced recoil. It also comes with the ability to penetrate through enemy targets, inflicting damage to several enemies at once.
Hyperion Splitters start with a low accuracy that improves as the weapon is fired for longer, though it's generally insignificant and mostly serves to control the spread. It also has a 50% bonus to critical hit damage (60% with a Hyperion stock).
Maliwan Splitters have an increase in elemental damage and chance, making it reliable for inflicting elemental status effects. It also has a continuous damage bonus that deals more damage the longer the trigger is held.
Tediore Splitters fire 6 beams per shot as opposed to 3 with a Non-Tediore body laser. When reloaded, the weapon is thrown and acts like a Tesla grenade.
