This means there is little reason to Diablo 4 Gold stockpile keys. If you already have access to an Echoing Hatred run, additional Trace of Echoes drops cannot be collected until the current one is used.

For that reason, players should generally run Echoing Hatred as soon as they receive access rather than saving it indefinitely.

How Echoing Hatred Works

Echoing Hatred is essentially a survival-based wave activity.

Enemies continuously spawn throughout the arena while a red progress bar tracks the encounter. As monsters appear, the bar fills. Killing enemies reduces it.

If the bar fills completely, the run ends.

Difficulty steadily increases through tiers that function similarly to Pit and Tower progression. As players advance, enemy strength scales upward and eventually reaches higher Torment levels.

Survival is important, but damage output is equally critical. Failing to eliminate enemies quickly enough will result in failure regardless of defensive strength.

Dying is even more punishing, as a solo death immediately ends the run.

Prioritizing Targets for Maximum Rewards

Success in Echoing Hatred depends heavily on target prioritization.

One of the most important objectives is destroying the large red portals that periodically appear around the arena. These portals dramatically increase enemy spawn rates, making it easier for the progress bar to d4 mats overwhelm players.
