Info from article by Bungie
Beginning Tuesday, July 06 Master Difficulty for Vault of Glass becomes available for all players!
How do you enter?
When signing in next Tuesday, Vault of Glass will offer a Master difficulty option to launch for you and your fireteam. While there is no minimum Power requirement to enter, enemies will be at 1350 Power, so you will want to earn some Pinnacle Power and raise your Artifact levels before attempting a run.
What can you earn?
First up, Master Vault of Glass unlocks the final Triumphs required for the Fatebreaker raid Seal and title. Once completed, players may equip their in-game title and purchase the Bungie Rewards pin if they so desire.
Second, Master Vault of Glass will also introduce Timelost weapons to Destiny 2. Timelost weapons can be comparable to Adept weaponry from Grandmaster Nightfalls or Flawless Trials Passages, but offer an additional perk in columns three and four for slightly more customization.
Complete Vault of Glass Challenges in the Master difficulty of the activity, and you will be rewarded. Each week will feature a specific Timelost weapon for you to hunt, rotating alongside the available challenge. Once you’ve earned a Timelost weapon, you may also purchase additional rolls from the chest at the end of the raid (on Master difficulty) using Spoils of Conquest. Note that these will be at a higher price than normal versions of these weapons.
Note by Kyber: The raid challenge next week is for the Gatekeeper encounter, so I believe the Timelost specific weapon for next week should be one of the following: Found Verdict, Fatebringer, or Hezen Vengeance. The armor that could drop next week, could be Helmet or Legs. Unless I am misunderstanding how this will work (if I am I will make sure to update that info here). Once I know the weekly rotation for the Timelost weapon I will add it to the weekly reset infographic, weekly reset post, and raid challenges page.

Please note – Weekly reward lockouts are shared between both Normal and Master difficulties of Vault of Glass. That means encounters, challenges, and hidden chests will only award gear the first time you complete them in either activity each week. They must be completed at Master difficulty first to earn Timelost weapons and stat-focused armor.
Lastly, armor from the Master difficulty of Vault of Glass will focus on specific stats, rotating weekly (This will be added to the weekly reset infographic, once I learn the weekly rotation). If you’ve been hunting a Prime Zealot Helm with a high spike in the Intellect stat, Master difficulty will give you greater chances for the distribution you’re looking for.
Get ready for a fight.
This won’t be a walk in the park if you haven’t dipped your toes into the Destiny 2 endgame before. Enemies will be tougher. They’ll be looking to put you down with more aggression. A few more Champions will be appearing to defend the Vault. More modifiers will be active, forcing you to think on your feet and come prepared. If you’re looking to increase your Power, make sure to complete your weekly milestones for Pinnacle rewards. One way to do that is in the Iron Banner. It’s active right now, so make sure to complete those bounties for additional Pinnacle rewards as you prepare for the raid!
Atheon will be seeing you next week. Good luck to all fireteams as they attempt their first Master difficulty raid.
