To upgrade Covenant gear, players will need to find certain NPCs, either in their Covenant's Sanctum or in Oribos, who can help them. They
will also need to have enough Renown and Anima to purchase the upgrade,
with upgrades gated until players reach certain chapters of the
Covenant campaign and earn the subsequent levels of Renown required.
Here's how to upgrade Covenant gear in World of Warcraft: Shadowlands.
Once players find theirs, they can drag the gear from its bag slot into the NPCs upgrading interface menu, or right-click to send it there.
The first few pieces of gear from a player's first campaign levels begin at Item Level 155, which is considered Rank 1 of 7. Players can
upgrade these ranks, which will improve the item level when they have
reached certain campaign chapters and have enough Renown and Anima to
spend. Not every piece will need to be upgraded, as players will get
some items from later campaign chapters that begins at a higher Item
Level and rank.
