Rat King Catalyst

Overview

Rat King Catalyst is an Exotic Catalyst Triumph in the Kinetic Weapons category. Its counter tracks 1,000 Rat King enemy defeats and includes a fireteam condition.

How to complete

Obtain the catalyst, equip Rat King, and arrange a fireteam whose other members also use the weapon. Have teammates defeat enemies in enemy-rich activities while keeping the sidearm equipped to receive the fireteam progress. Coordinate target groups instead of splitting up across unrelated activities, and continue until the required counter is complete. Apply the completed catalyst in the weapon's menu.

Acquisition

The catalyst can drop from Nightfall strike completions.
