The Best Way to Complete Invading Forces in Diablo 4 Season 11

The fastest and easiest method to complete Invading Forces is by Diablo 4 Items farming The Undercity in a party.

This approach is highly effective due to three key factors:

1. Enemy Density
2. Affix Spawn Rate
3. Shared Kill Credit in Groups

Why The Undercity Works So Well

The Undercity features massive clusters of enemies packed into tight spaces, many of which frequently roll the required Invading Forces affixes. Instead of hunting for isolated spawns in open-world content, you're constantly surrounded by eligible enemies.

In practical testing, this method dramatically accelerates progress. In a single Undercity run, it's possible to gain dozens of kills toward the objective. Players regularly report jumping from single-digit progress to over 50 kills in just a few runs.

Because Undercity runs are short and repeatable, you can chain them back-to-back until the objective is complete.

Play in a Party for Maximum Efficiency

While you can complete Invading Forces solo, forming a party makes the process significantly faster.

Benefits of Group Play

Faster clears due to combined damage
More enemies defeated per minute
Kill credit counts as long as you're nearby
Easier survivability of greater difficulties

Even if your party rushes through content aggressively, the kill credit still applies as long as you're in range. This means support builds and lower-geared characters can still progress efficiently.

Finding a group is usually easy, even during off-hours. Alternatively, you can create your own party and buy Diablo 4 Items invite others who are also working on seasonal objectives.
