Highlights

  • Lucent moths are the new Hive-themed weapon in Destiny 2 Season of the Witch, called Ex Diris, an Arc light grenade launcher found in the energy slot.
  • Ex Diris fires Arc projectiles that transform into enemy-seeking moths, blinding targets and automatically filling the magazine from reserves, reducing the need for reloading.
  • To obtain the Ex Diris Catalyst, players need to complete a quest from Banshee-44 in the Tower, involving defeating multiple targets rapidly, calibrating data, and defeating targets with Ex Diris itself. The Catalyst enhances the weapon's enrage effect for Arc builds.

It was only a matter of time before Lucent moths became a part of a guardian's armory in Destiny 2. The newest, grittiest Hive-themed weapon and the seasonal weapon for Season of the Witch is Ex Diris, an Arc light grenade launcher found in the energy slot.

The launcher fires little Arc projectiles that turn into enemy-seeking moths, which in turn blinds targets. It also has the ability to automatically fill the magazine from reserves, which means less reloading for players overall. Corrupted Nucleosynthesis is its Intrinsic trait, which boosts its rate of fire when dealing damage or when the player takes damage—also known as "enraged". The Catalyst for Ex Diris further tweaks this enraged effect, once players complete the quest in Destiny 2

How To Get The Ex Diris Catalyst

Destiny 2 Grenade Logic Quest Step 1

After claiming the Ex Diris grenade launcher from the seasonal pass, Banshee-44 will have a quest waiting for the player in the Tower. Speak with him to pick up the Grenade Logic quest. Here's what each three steps of the quest entails.

Destiny 2 Grenade Logic Quest Step 2

Step 1: Defeat multiple targets rapidly and defeat targets without dying. This can be done with or without using the Ex Diris.

  • 20 rapid multikills
  • 25 kills without dying

Step 2: Calibrate data and defeat targets with the Ex Diris. Make sure to get these kills with the weapon itself. Calibration needs to happen in activities like Vanguard ops, Crucible modes, Gambit, or seasonal activities.

  • 200 calibration data
  • Targets defeated

Step 3: Head back to Banshee-44 in the Tower.

  • The gunsmith will grant you the Ex Diris Catalyst.

Once players have the Catalyst, it needs to be upgraded in order for Masterwork to become available. Ex Diris requires 400 kills for the Catalyst to unlock for the weapon itself. Make sure to put on Special ammo finders for this one to make the grind a little bit more bearable.

What The Ex Diris Catalyst Does

  • Berserk Rush: Ex Diris becomes enraged at a quicker rate if the player is Amplified. Final blows grant Amplified to the player.

The Catalyst makes Ex Diris even more compatible with Arc builds, as it gains some synergy with Amplified. The enrage is easier to gain whenever players activate Amplified, and they can keep reactivating this status effect by simply earning more kills. This is a very powerful tool for Arc builds, even if the weapon itself isn't the best or the strongest Arc grenade launcher around. Regardless, its Catalyst is certainly worth the endeavor.

Destiny 2 is available on PC, PlayStation 4, Xbox One, PlayStation 5, and Xbox Series X/S.
