Want to get your hands on that cool looking Vex Mythoclast in Destiny: Age of Triumph? Of course you do, and we're here to show you how to increase your change at nabbing it.
To improve your chances, Arekkz says to make use of the new Age of Triumph consumable Knuckles of Eao which are a one per week drop. For example, you can grab this item from Vault of Glass out of the first chest when you walk in the door. If you did Crota's End Raid, it came from the Abyss
Knuckles of Eao will increase rewards from the next raid encounter you complete in a weekly, featured raid. They won't stack, obviously.
Anyway, use one before you fight Atheon in Vault of Glass and it will increase the drop chance for a 360 Light Vex Mythoclast Exotic Fusion Rifle. If you see this show up at the Postmaster for you, once you get your hands on it, infuse it in order to bring it up to 400 Light.
You can see the rifle in action around the 2:24 mark in the video.
