Rat King Catalyst grants +20 aim assistance, +20 recoil direction and starts health regeneration on Vermin invisibility. This is the nastiest sidearm in the game with tons of cool interactions (invisible Titan shoulder charge, for example).
This service requires you to have the catalyst on your gun. If you want us to get it for you, please add the corresponding option.
Rat King catalyst takes 500 kills to unlock. However, only fireteam members using it can progress your own Rat King.
