Although we're only beginning to discover D2R Items how rewarding the new dungeon is and it's great to be able to see Diablo Immortal offering a huge playing area to the game rather than dribbling in a few more items to keep players occupied.
This update also offers an entirely new set of items Gloomguide's prize, which brings the total amount in games to nine. The new set is focused on expanding your options for movement, in turn increasing your damage through new options to enter and exit combat. It's an engaging way to play since it allows for a more active play style.
The update's last major feature is the brand new exploration system for players to discover the Warband Castle. With two to eight others, you'll battle through 16 rooms of monsters as well as an epic battle to collect heirlooms to buff your warband.
In the end, Forgotten Nightmares appears to be a major update to Diablo Immortal. Alongside the major changes, it also includes various minor additions which include new cosmetics, events, raid bosses, and more. Unfortunately, as echoed by several community members the constant concentration on warbands won't be able satisfy all players. If you're a fan of playing alone, you'll probably benefit from the new items set, since you'll have to group up Diablo 2 Resurrected Items to experience the new dungeon, or Warband exploratory system.
