Title: Diablo IV - Vessel of Hatred - Dark Citadel - Dominion of Zagraal Dungeon
Description:
The Dominion of Zagraal is the last of three wings in the Dark Citadel, the new area for high-end content. These dungeons are quite challanging, especially the boss fights. The bosses involve various strategies the players have to follow. These dungeons cannot be completed alone - you need to have at least two players, although four are recommended.
The Dominion of Zagraal uses Soul Siphons, where you have to stay near them in order to charge them. And there are now Spell Guardians, which have to be defeated. They drop a Counterspell which needs to be used to reflect Soul Orbs back to where they came from.
The same mechanics are applied to the boss (Zagraal, the Eternal). Soul Siphons have to be charged and then the Ritual Sigils need to be dispelled by using the correct Sigil with the correct Ritual. Then Zagraal starts shooting out Soul Orbs. You have to defeat a Spell Guardian, grab his Counterspell and shoot the orb back to Zagraal. Then you are brought to the Realm of Oblivion where you can do damage against him. Then you have to activate the Conduit by standing on the plates near it to get back, slay countless enemies to activate the Soul Siphons. Repeat until he is defeated.
