I figure we should compile some information on how to get these and where.
So it looks like the catalysts are found in 4 different ways, those being killing strike bosses, finishing the raid, winning in the crucible, and killing any pve opponent.
The ones found by killing strike bosses are:
Coldheart
Merciless
Wardcliff Coil
Riskrunner
Prometheus Lens
Huckleberry
The ones found by winning in the crucible are:
Vigilance Wing
The Colony
Jade Rabbit
The ones for killing enemies of humanity are:
Tractor Cannon
D.A.R.C.I.
Crimson
Borealis
And there’s only one found by “currying the emperor’s favor” which I can only assume is completing the raid. That gun is Skyburner’s Oath
