To keep it from detonating like a thousand pounds of TNT, the Shard Diffactor is limited to short, controlled bursts, but don't let that depress you - it's powered by a 12-pound chunk of Ommoran Heartstone, and is able to vomit forth thick beams of raw energy, reducing anything in it's path to a mound of cinders
— Weapon Description

The Shard Diffractor is an unlockable secondary weapon for the Engineer. It is an intricately designed laser cannon consisting of various electrical and mechanical components. A shard of Ommoran Heartstone rests in a central chamber and is surrounded by three plasma torches rigged with wiring. Upon using the weapon, the shard becomes superheated which emits a beam of destructive energy that incinerates enemies.

In addition to having infinite range, the Shard Diffractor inflicts continuous damage onto any target impacted by the beam along with anything surrounding the impact point. The beam will also cause an enemy's temperature to rise, eventually resulting in them being ignited. As the weapon description claims, slain enemies will be reduced to a rapidly-dispersing cloud of ash, preventing some on-death effects (such as the Praetorian's gas cloud) from occurring.

The Shard Diffractor also features a battery with a maximum charge capacity rather than a conventional magazine; firing the weapon drains the battery while releasing the trigger will automatically recharge the battery, which draws from the weapon's total capacity. Furthermore, the battery must be fully charged in between uses and there is a brief spinup delay before the weapon can begin firing.

Unique Modifications

Bio-mass Converter

Bio-mass Converter is a tier 5 modification that refunds 3 ammo each time an enemy is killed.

Cooldown: 0.25s

Excluded enemies include:

Unique Overclocks

Feedback Loop

Frame Overclock Balanced.png
Icon Upgrade Area.png

Feedback Loop is a balanced overclock. For every second that the beam is continuously held, the weapon will gain a stack that grants:

  • +1 Area Damage
  • +0.3m Radius

There is no limit to the amount of stacks that can accrue over time and all stacks will reset once the Shard Diffractor stops firing.

Volatile Impact Reactor

Frame Overclock Balanced.png
Icon Upgrade Special.png

Volatile Impact Reactor is a balanced overclock. Whenever the beam touches the ground, it will be turned into hot magma for 7 seconds in a 0.3m radius. The magma deals 5 Fire and 5 Heat damage every 0.1-0.15 seconds, equating to 40 DPS + 15 DPS from the On Fire status effect. The magma also slows any enemy in its radius by 0.7x (30%).

Plastcrete Catalyst

Frame Overclock Unstable.png
Icon Upgrade Explosion.png

Plastcrete Catalyst is an unstable overclock. When shooting any platforms, splash damage and damage radius of the Shard Diffractor's beam are boosted by 50%. After shooting at platform material for one uninterrupted second the beam will trigger an explosion centered on the point of contact that deals tremendous damage and carves a small amount of terrain.

Explosion Damage:

  • Damage Conversion Bonus: 150 Area Disintegrate (no radial flag, no fall-off).
  • Damage: 150 Area Explosive.
  • Max Damage Radius: 3.5m.
  • Minimum Damage: 25%.
  • Damage Radius: 5m.
  • Friendly Fire Multiplier: 25%.
  • Armor Damage: 50%.
  • Fear Factor: 100%.

Overdrive Booster

Frame Overclock Unstable.png
Icon Upgrade DamageGeneral.png

Overdrive Booster is an unstable overclock. Pressing the reload button while firing will activate Overdrive Booster, which will do the following:

  • Set movement speed to 0
  • Increase ammo consumption by 1
  • Multiply damage output by x2.5
  • Cause the beam to continuously fire
  • Require an extra 1.5s to recharge

Similar to Automated Beam Controller, manually stopping the beam by swapping to another weapon or using the pickaxe will consume 50% of the remaining charge.
