Diablo 4 Season 11 has some frustrating seasonal objectives, such as Invading Forces. It tasks you with defeating enemies with very specific affixes (Infested, Illusory, Anguished Souls, Sinful Torment), and you have to kill 200 of them on Hard or higher difficulty. It’s not the difficulty that’s tripping players up, but actually finding these enemies. While they can spawn in a variety of places, there is one place that we’ve found that makes it not only fast, but easy.
We also recommend farming Invading Forces objective kills in a party, so the clears are even faster and easier. If you’re struggling to complete Invading Forces in Diablo 4 Season 11, here’s what we recommend to stomp past this objective in no time at all.
How to best complete Invading Forces seasonal objective in Diablo 4 Season 11
If you want to take care of Invading Forces in no time at all in Diablo 4 Season 11, I recommend clearing through Undercity in a party. That does hinge on you having the Vessel of Hatred expansion, though. The reason for this is the sheer glut of enemies that all show up clumped together.

For context, when doing this myself, I went from 6 enemies defeated to 32 in one run, then 53 defeated in the second run. It really went incredibly fast, even if you’re running with people that just push as hard as possible to the end. Even in the early hours of the morning, it’s not hard to find a party for the Undercity.
You can also form a party yourself, and invite others to help you out. It’s a great place to level up your seasonal rep, and clearing Andariel over and over will work towards ranking up her Divine Gift, if that’s something you’re interested in. As long as you're relatively near the enemies being defeated, it should count. It certainly did for me.
Just keep running Undercity and you’ll be done in no time at all. It’s a short activity, and with a full group you’ll smash it apart easily, and get Invading Forces in Diablo 4 Season 11 as efficiently as possible.
