Bungie has tied hands with Discord to celebrate the launch of Destiny 2 Revenant Act 1. Before October 22, you simply need to play the game while being connected to Discord to earn the exclusive Celestial Ties Shader.
While this is a pretty simple quest to complete, if you are stuck, you can use our guide to clarify your doubts.
Destiny 2 Discord Shader: Celestial Ties: How To Get Its Code
The very first thing that you need to do is connect your Discord account with Bungie or the platform that you are playing on. You can do this by going to Discord settings and then, navigating to Connections tab.
After that, head over to the Discover tab that you will find at the bottom of the list of your joined servers. Next, click on Quests and claim the Celestial Ties Shader quest. Play the game for 15 minutes and you will get the option to get a code for the shader.
Copy the code and go to bungie.net/redeem to redeem your reward. Once you do it, you will get the message saying, "Success! Destiny 2 Shader — Knight-Errant." While this name is incorrect, if you go into the game, you will get the correct item.
To collect Celestial Ties shader, simply launch Destiny 2 and go to Special Deliveries terminal kiosk in the Tower and interact with it.
