History of Tarrabah Catalyst

Overview

Tarrabah Catalyst is the upgrade record for Tarrabah, an Exotic Solar Submachine Gun. Complete its 700-target objective using the weapon after obtaining the catalyst.

Acquisition

The catalyst was added in June 2026. It can drop from Vanguard Ops, Crucible and Gambit, or from Exotic Order payouts in the Seasonal Hub. Obtaining the catalyst and completing its weapon-kill objective are separate steps.

How to complete

Equip Tarrabah and defeat 700 targets with it. Combatants in ordinary enemy-dense activities count; the objective does not require Guardian kills. Keep the weapon equipped while clearing groups to build and use Ravenous Beast. Once completed, the catalyst grants Ambitious Assassin, allowing rapid kills before reloading to overflow the magazine.
