With the arrival of Diablo 4: Lord of Hatred, Blizzard introduced several changes to the endgame experience. The new War Plan system revamped progression across existing activities, but only one truly brand-new endgame activity arrived with the expansion: Echoing Hatred.

Despite being one of the expansion’s most rewarding activities, many players have barely experienced it. Some adventurers report never seeing a single entry key drop, while others have only encountered one or two throughout their entire playtime. The problem is that the game does a poor job of explaining how the activity works, where the keys come from, and what rewards make it worth running.

For players looking to maximize their loot, collect exclusive cosmetics, and push their builds through increasingly difficult waves of enemies, Echoing Hatred offers a unique challenge. Understanding how to access it and how to approach it efficiently can dramatically increase its value.

This guide covers everything you need to know about Echoing Hatred, Diablo 4 Items, key farming strategies, gameplay mechanics, and areas where the system could still be improved.

Why Run Echoing Hatred?

Before discussing strategies, it is important to understand why players should care about Echoing Hatred in the first place.

The activity offers several layers of rewards that go beyond standard loot drops.

Goblin Plunder Bags

The primary reward comes from Goblin Plunder Bags.

Every Treasure Goblin killed during the event contributes directly to your final rewards. At the end of the run, players receive one Goblin Plunder Bag for every goblin defeated.

These bags can contain:

Dungeon Keys

Seals

Charms

Mythic Seals

Various crafting materials

Additional valuable loot

Many players consider Echoing Hatred one of the most efficient sources of these resources. Some players have even obtained Mythic Seals directly through these reward bags, making the activity particularly attractive for endgame progression.

While the reward chest itself provides standard loot, the Goblin Plunder Bags are the real prize.

Unlocking the Crab With a Knife Pet

One of the most entertaining rewards in Diablo 4 is hidden within Echoing Hatred.

Players who reach Tier 60 during a run unlock the legendary Crab With a Knife pet.

This bizarre crustacean companion has quickly become a fan favorite. Its battle-scarred appearance and amusing animations give it far more personality than many premium cosmetics. The pet casually tosses its knife between claws while following the player around Sanctuary, creating one of the most memorable cosmetic rewards currently available.

The best part is that it is earned entirely through gameplay rather than through a shop purchase.

For many players, this pet alone is worth the effort required to push deeper into the activity.

How to Unlock the Howling Mouth of Madness Portal

Echoing Hatred also contains a hidden cosmetic reward known as the Howling Mouth of Madness Portal.

Unlike the pet, this reward requires a specific sequence of actions during a run.

Throughout every Echoing Hatred instance, four shrines spawn somewhere in the arena:

Protection Shrine

Artillery Shrine

Lethal Shrine

Channeling Shrine

The locations change from run to run, but all four shrine types are always present.

To unlock the portal, players must activate each shrine during specific difficulty ranges.

Required Shrine Sequence

Tier 1–9

Use the Protection Shrine

Tier 10–14

Use the Artillery Shrine

Tier 15–19

Use the Lethal Shrine

Tier 20–24

Use the Channeling Shrine

Successfully activating the shrines within these ranges triggers achievement notifications and unlocks the portal reward.
