How to get Rat King (The Rat King's Crew Quest) - Destiny 2

Rat King is an exotic Sidearm.

You need to complete Quests given to Sloane, completing the "Enemy Of My Enemies Quest".

Once you complete the quest, you will be given the "Rat King's Quest", the quest reads in riddles which may be difficult to figure out.

The Rat King's Crew Quest:

"The Rat King's Crew / Runs to and fro / Good girls and boys / Know where to go / Pick up your toys and darn your socks / On errands of woe, on errands we walk" - Old Children's Rhyme.

You need to complete 3 Patrol Missions

You need to complete 2 Public Events

You need to complete 2 Crucible Matches

Once you have done this, you need to complete the Nightfall Strike of the Week with 5 Minutes left on the clock.

Once you have done this, the Exotic Sidearm will be added to your inventory.

The nice perk of using Rat King, is that if other players near you are also using Rat King the power of the weapons will increase, as well as the fire rate which is faster. Also if you reload just after getting a kill, you will go invisible for around 3 seconds.
