One of the most popular PvE activities in Destiny 2. Very complicated, tactically loaded 6-Guardian Raids. Doing them is very time-consuming, tough, but totally worth it. You will get tons of loot after any Raid, including a chance to get a random or raid-specific exotic weapon.
The problem is that you have to find a reliable team, as there is no matchmaking for Vault of Glass. Overgear is ready to provide you with effective raid carry services done by a fireteam of professional boosters. Buy Vault of Glass Boost, complete any amount of runs you want, and get all the rewards.
Yes, you don't need to have any expansion to play it.
It's on the Venus planet, if you want to start the raid, click on the "Legends" in Destinations.
