Echoes Act 3 adds a few new guns to Destiny 2, including Chronophage, a new Void trace rifle that's built for disintegrating enemies. It's a solid alternative to some other, tougher-to-get trace rifles, like the Rise of Nightmare raid's Acasia's Dejection. The Chronophage god roll is especially good in PvE, with a few perks that are great for synergistic Void builds to keep you shielded and happy as you zap your way through hordes of opponents.
The launch of Echoes Act 3 adds Chronophage to the episode's loot pool, meaning you'll start to see it drop from Echoes activities: Breach Executable, Enigma Protocol, and Battlegrounds. The gun can also come from Echoes Engrams you'll earn all over the solar system, but in order to focus those engrams into Chronopage when you visit Failsafe, you'll need to complete new Nessus Specimen quests to unlock its focusing upgrade. Like the other guns from Echoes, Chronophage is craftable, so you can get it with your pick of enhanced perks.

Masterwork: Stability
Trace rifles live and die by the stability stat, since they fire a single concentrated laser beam you want to hold on a specific target as long as possible, so look to boost Chronophage's stability whenever possible. The combination of Repulsor Brace and Destabilizing Rounds is always great in a weapon for clearing small enemies, particularly if you're running a Void build, since you get to turn enemies Volatile while constantly creating an overshield for yourself as you rack up kills. Chronophage also includes the Echoes origin trait Radiolaria Transposer, which combines well with any set of perks that let you kill a lot of enemies quickly, as multikills cause targets to explode and create pools of radiolaria on the ground.
