How do you access the Diablo 4 Dark Citadel? This endgame PvE activity sees you team up with friends to tackle its difficult bosses and take down hordes of enemies throughout three wings. Resting at the bottom of a huge crater left by the Mage Clan civil war, the Dark Citadel is home to the Khazra, or Goat Demons, who are attempting to summon their overlord. It's your party's job to prevent that from happening.
Diablo 4's Dark Citadel is Diablo 4's first multiplayer-focused content, introducing the game's most challenging encounters. It contains complex mechanics that require some figuring out rather than being able to approach them with brute force. You'll want one of the strongest Diablo 4 builds to take on these difficult activities. Still, we've found success using the Diablo 4 Spiritborn class - the newest one in the game - and its overpowered Centipede guardian.
