Here, we mainly introduce the endgame systems in Diablo IV.

1. World Bosses

World bosses are large events found in the open world that you must defeat with a large number of players. At the start, three different world bosses will be available.

2. Nightmare Dungeons

Inspired by Diablo III's Greater Rifts, Nightmare Dungeons in Diablo IV are similar to regular dungeons but with added difficulty and dungeon properties. Each Nightmare Sigil represents a different dungeon. The difficulty levels are linked to the Nightmare Sigils and will increase indefinitely, determining the rarity of item drops. Dungeon affixes, which can also be found on Nightmare Sigils, modify the dungeons by altering the player, foes, and/or the environment. Here are a few dungeon affix examples:

These Nightmare Sigils can be gained by completing assignments at the Tree of Whispers. More information on the Tree of Whispers can be found in the next section. When you complete a Nightmare Dungeon you will be rewarded with a more powerful Nightmare Sigil.

Preparation and strategizing will be essential because you will know which dungeon you are entering, the monsters you will confront, the difficulty level, and which affixes you will face.

New Nightmare Dungeons will become available to explore as you progress through the World Tiers.

3. Whispers of the Dead - Tree of Whispers

The Tree of Whispers has frequently cycling world objectives, known as Whispers, that are displayed on your map and reward you with experience, gold, and varying amounts of Grim Favors. 10 Grim Favors can be exchanged for various loot and experience at the Tree of Whispers.

The types of Whispers on the map will vary regularly throughout the day and each will give a different set of rewards and experience for finishing it.

The Whispers of the Dead system will become available after completing a specific chapter of the main storyline.

4. Helltide

Helltide is a region-wide event that unlocks after completing World Tier Three: Nightmare difficulty. During the Helltides, the landscape will reflect demonic activity, and monsters will be more numerous and difficult to kill, but they will also drop better loot.

Monsters in a Helltide may drop Cinders, a currency that can be spent to open Helltide Chests scattered throughout the region. Helltide Chests grant you items that are unique to a specific item slot, such as Torso, Legs, or Two-Handed Weapon. If you die while carrying Cinders, they will fall to the ground and must be reclaimed.

5. World Tiers

World Tiers exist to ensure that the difficulty of the world matches your character level's power. When entering the game or at the World Tier Statue in major towns, the difficulty can be changed. To access the more difficult content, you must first prove your worth by completing a specific dungeon (with a difficult boss at the end).

Level 1 will grant access to World Tier 1 and 2. World Tier 1 is for newcomers to ARPGs and the franchise, while World Tier 2 is for veterans.

6. Leaderboards

Leaderboards will be more in the direction of the Diablo III Seasonal Conquest leaderboards, with a focus on relevant leaderboards for certain activities/challenges and a modest quantity of people competing for it. Rather than having players compete for the top spot out of a million. This is referring to Greater Rifts in Diablo III, which automatically put you into the tournament if you complete a level high enough to place among the top 1000 in a given bracket.
