What Is the Invading Forces' Seasonal Objective?

The Invading Forces' objective tasks players with Diablo 4 Items defeating enemies that possess one of the following special affixes:

Infested
Illusory
Anguished Souls
Sinful Torment

To complete the objective, you must defeat 200 total enemies with these affixes while playing on Hard difficulty or higher.

While these enemies technically appear in multiple types of content, their spawn rate is inconsistent. Many players report going long stretches without encountering more than a handful at a time, making traditional farming methods inefficient.

Additional Benefits of Undercity Farming

Completing Invading Forces in the Undercity offers several side benefits that make this method even more appealing:

Seasonal Reputation Progress

Repeated Undercity runs contribute toward seasonal reputation gains, helping you unlock rewards faster.

Divine Gift Progression

If you're working on leveling Andariel's Divine Gift, repeated clears naturally contribute to its progression.

Experience and Loot

The Undercity remains one of the most efficient sources of experience, gear upgrades, and crafting components. Instead of farming a disconnected objective, you're actively improving your character and building a stronger inventory of Diablo 4 Items.

This efficiency is especially valuable for cheap d4 mats players trying to minimize grind or avoid relying on external shortcuts like choosing to buy Diablo IV Items instead of farming.
