In the Warmind expansion, Destiny 2 introduced Exotic Catalysts, special modifiers that make Exotic weapons even better. However, each Exotic has its own Catalyst, as well as a hidden condition that will further upgrade it to Masterwork.

Here's where to find the Exotic Catalyst for your favorite weapon in Destiny 2, and how to turn it into a Masterwork.

Destiny 2 Exotic Catalysts and Masterwork Upgrade Guide

Each individual Exotic weapon has its own Catalyst, although not all of them have been added to the game yet, and that Catalyst in turn has a specific place where it drops. Just about everything you can do in Destiny 2 has a potential Catalyst drop attached to it, such as Patrols, Strikes, Nightfalls, raids, and the Crucible.

You'll want to find your Exotic of choice on the following list, then keep after its connected activity until you get the Catalyst you want.

Once it's installed, the Catalyst instantly upgrades your Exotic in at least one specific way. From there, once you satisfy the attached conditions, the Exotic weapon is upgraded to Masterwork tier.

Note that items in boldface under Catalyst Effect in the following table are the names of perks that are actually added to the Exotic weapon by its Catalyst.

At time of writing, Exotic weapons without Catalysts include Arbalest, Deathbringer, Heir Apparent, and the Queenbreaker. However, Bungie is still working on adding more Catalysts to the game, so sooner or later, every Exotic will have a mini-upgrade quest to call its own.

The Guardian Games are still underway in Destiny 2, although it's going into its final week. Go in prepared with our guides and tips, including:

The Titans are currently winning Destiny 2's Guardian Games, as I'm writing this, and are overpowering the early favorite, the Hunters. Bungie is sweetening the pot, however, by doubling the points for each daily winner. It's still anyone's match. If you play a Hunter or a Warlock, coordinate your plans for a come-from-behind victory with our squad via our official Twitter, @PrimaGames.
