History of Mastery

Overview

Mastery is a Triumph in Destiny 2 that requires completing three activities on Master difficulty. Progress is shown as activities completed out of 3.

How to complete

Choose any three activities that offer a Master difficulty and complete each one on Master. Lost Sectors are a practical option: each one must be finished once on normal difficulty before its higher tier opens, and only one Lost Sector per day is offered on Legend or Master. Equipment is locked for the whole run, so set your loadout before entering. Revives are limited, with one granted per Champion or Lightbearer Hive enemy killed, and all remaining revives are lost after 15 minutes. Solo completions can also reward Exotic armor.
