Weekly Milestones
Milestones are essentially missions in Destiny 2. There are weekly Milestones which offer up a reward called Powerful Gear. This is basically a package that provides legendaries (and, rarely, exotics) that drop higher than 265, and usually higher than whatever your current Light level is. Each one focuses on a different part of the gameplay experience:
Flashpoint – A weekly exploration Milestone. Simply complete public events (doing Heroic ones makes this go by quicker) and you’ll earn some sweet loot.
Call to Arms – This is a weekly crucible objective. Just create a fireteam and complete a bunch of matches.
Nightfall – Not for the faint of heart. Take on a strike with some soul-crushing modifiers.
Clan XP – Weekly challenges for clans.
Doing all of these will have you rolling in high-level gear that will see your legend truly become something to remember.
