Indeed, the various Hard Mode versions of these fights will add an additional +7 ilevel to the gear that drops. Just in case you didn’t think that Tazavesh, the upcoming megadungeon in patch 9.1, was going to be hard enough, worry not - you’ll be able to make it even harder with a questline that will allow you to activate Hard Mode for all fights in the dungeon, giving you another way to increase the item level of the gear that drops besides simply doing a higher key.
