The tenth week of a Destiny 2 season traditionally delivers one final handful of seasonal objectives to pursue. For Season of the Seraph during its tenth week, that list has just three objectives to knock off your list.
One of these objectives, EDZ Activities, is relatively easy to complete, and if you’ve been busy with Vanguard activities, then Vanguard Ornament will likely be completed already and you can collect a small pile of Bright Dust for your efforts.
You can tackle seasonal challenges at your own pace, as they’ll only expire once the season concludes in February. If you decide to take a break from Destiny 2, you can always return and complete multiple challenges at the same time after a few weeks of rest.
