Destiny 2: Ranking All Exotic Weapons From Worst To Best
10. Rat King
The Rat King is an exotic you will be able to earn through a chain of quests on Titan after you've completed the story. The last task is the most challenging, which requires you to complete a Nightfall with five minutes remaining, but with the right group it's a cake walk.
As an exotic sidearm, you'd think the Rat King would leave a lot to be desired, but the gun actually delivers in its perks. First, reloading after a kill grants you a short period of invisibility, which is a nice perk for anyone who is playing as a Titan or Warlock.
The real punch comes in its Rat Pack perk however. This perk enables the gun to grow stronger if members of your fireteam also have it equipped, and this can stack up to six times. It's a pretty noticeable increase as well when you have a full group running it. It's not a gun you'd want to venture into PvP with, but running into PvE with a stack of power increases is something you may want to try for yourself.
