Grim Favours are a currency that can be exchanged for loot at the Tree of Whispers. On the World Map, Whispers will be visible giving tasks to complete for rewards of XP, gold and 'Grim Favors'.

However, they will be made available to all players for this testing phase. Whispers of the Dead appear to be side quests, which Blizzard has said will not be available until players have reached a certain point of the main quest.There will be increasing difficulties of sigils available in the game upon players completing progressively more difficult Nightmare Dungeons. The sigils will add modifiers to the dungeons, and so far sound rather like Legendary Crests in Diablo Immortal - adding a layer of difficulty to the challenge and increasing the quality of loot dropped from your enemies. Players must first locate a Nightmare Sigil which will lead them to the dungeon location in Sanctuary. Nightmare Dungeons are Diablo 4 dungeons of, you guessed it, Nightmare difficulty.Death will result in the player dropping their Cinders and being required to reclaim them. Enemies will also drop 'Cinders' an in-game currency that can be used to open Helltide chests throughout the affected region. In Helltide, defenders of Sanctuary will fight enemies of an increased difficulty and spawn rate, in return for higher level loot.

Helltide will be a region-wide event available to players who have reached the Nightmare difficulty in World Tier Three, and sounds very akin to the Terror Zones that have recently been added to Diablo 2: Resurrected.
