In Season 2 of Diablo 4, also known as the Season of Blood, Blizzard introduced many exciting features, including Vampiric Powers, the Blood Harvest event, and five powerful bosses. Among them, Lord Zir stands out as a highly sought-after target, renowned for his unique item drops and exclusive cosmetics.

This guide will walk you through the process of summoning Lord Zir, one of the most challenging endgame bosses, also known as the Dark Master. As the leader of a vampire cult, Lord Zir commands an army of Bloodseekers, threatening to overrun Sanctuary. To stop him, players must engage in a difficult battle. Read on to learn how to unlock Lord Zir and the rewards you can earn by defeating him.

How to Summon Lord Zir in Diablo 4

Since Lord Zir is an endgame boss, you will need to be in World Tier 4 to face him. Summoning Lord Zir requires Exquisite Blood, a rare resource that can be obtained from Legion Events, World Bosses, and Helltide Bosses. These events are conveniently marked on the game map, making them easy to locate. Among these, Helltides and Legion Events offer the fastest way to farm Exquisite Blood, so it's advisable to focus your efforts there.

Common Legion Event locations include:

Carrowcrest Ruins in Scosglen

Crusader's Monument and Norgoi Vigil in Hawezar

Dilapidated Aqueducts in Kehjistan

Haunted Wreckage on the coast of the Dry Steppes

Kor Dragan in Fractured Peaks

Once you have collected nine Exquisite Blood, follow these steps to summon Lord Zir:

Travel to the Darkened Way in Kyovoshad.

Interact with the Altar found inside the Darkened Way.

Sacrifice the Exquisite Blood at the Altar to summon Lord Zir.

Remember that Lord Zir can be summoned multiple times, but each summoning requires the same amount of Exquisite Blood. Therefore, it might be strategic to save up for future summons if you plan to farm him extensively.

How to Summon Tormented Lord Zir

For those looking for an even greater challenge, the Tormented version of Lord Zir awaits. To summon this powerful variant, you will need 21 Exquisite Blood (three times the normal amount) and a Stygian Stone, another rare resource. The summoning process is similar:

Return to the Altar in the Darkened Way.

Use the second tab in the summoning interface to sacrifice the required materials.

Summon Tormented Lord Zir, a level 200 version of the boss, capable of dropping Mythic Unique Gear.
