Lord Zir Boss Guide

Welcome to the Lord Zir (Dark Master) Boss Guide. Here you will find all the information to gather summoning materials, summon the Boss, and successfully defeat it.

Basic Information

• Requires Torment 1 or higher.
• Activity Recommended: Collect components from Tree of Whispers, World Bosses, Blood Maiden in Helltide, the Undercity, or slaying Elites Monsters on Torment Difficulties
• Summoning Material: 12x Exquisite Blood

• Element Type: Fire
• Cosmetic Reward: Diadem of the Ancient Helm Cosmetic

In order to summon Lord Zir, collect Exquisite Blood from completing various endgame activities such as Tree of Whispers, World Bosses, Blood Maiden in Helltide, the Undercity (using a Tribute of Titans), or slaying Elites on Torment Difficulties. Once you have 12 Exquisite Blood, you can summon him to fight.

To challenge Lord Zir and his vampiric minions you need to make your way to the Darkened Way to the East of Kyovashad. Once within travel to the Ancient's Seat, you'll find Lord Zir by fighting your way to the heart of the dungeon.

Before heading out consider a quick stop at the Alchemist to pick up a Elixir of Fire Resistance II to help counter his Fire-based abilities.

Each Boss's health bar has multiple breakpoints. Once a breakpoint is reached, the red arrow flips up and turn grey. This indicates that you are in the next phase of the fight, while also dropping multiple healing vials. Each phase is more challenging than the last.

Stagger Bar Mechanic

Immediately beneath the health bar is a stagger bar, this slowly fills when Crowd Control (CC) is dealt. Once full, the Boss is rendered helpless for a short window of time. Use this opportunity to unleash as much hell as you possibly can.

Pay attention to each of the attacks used by Lord Zir (Dark Master)! The following section guides you through the boss's most dangerous abilities.

Lord Zir's Abilities

Initially, Lord Zir attacks you alone, but as the fight progresses he is joined by vampiric minions. Being hit by these mechanics gives you a stacking Tormented debuff that increases your damage taken, so avoid them at all costs!

• Slap - Taking offense to your very existence, Lord Zir attempts to slap intruders in his domain.
  • This doesn't hit very hard, but you can position behind the boss to avoid it.
• Blood Rain - Lord Zir hunches down and flaps his wings to release a rain of blood upon the arena.
  • Watch for where the projectiles land and avoid the puddles.
  • The puddles move from time to time, and interact with some of his other abilities.
• Blood Talons - After assuming a crab-like stance, Lord Zir generates claws of blood and scythes targets in front of him.
  • This hits fairly hard, but is easy to avoid as you can move behind him when he rears up.
• Wing Blast - When he reaches 66% health Lord Zir gains a new ability. He teleports away from you and begins to charge a powerful wing blast which deals damage and knocks you back.
  • Look for the telegraph on the floor, initially it tracks your movement but the position becomes locked shortly before the ability activates.

While Lord Zir doesn't gain many new abilities over the course of the fight it can become increasingly difficult to deal with him, the minions he summons, and the environmental effects. However, the presence of these minions means that you can proc on kill effects liberally to enhance your damage against the boss.

Minions & Environmental Hazards

During the encounter, you'll have to deal with bats, Vampire mages, Blood Seekers, and various environmental hazards. He'll summon a Blood Orb or Blood Seeker each time he loses around 20% health, and sometimes summons both at once.

• Blood Puddles - From time to time the blood puddles move around the arena, merging together and emitting projectiles which inflict Vulnerable.
  • Avoid standing near puddles, and watch for incoming projectiles.
• Blood Orbs - As he takes damage, Lord Zir summons blood orbs which do one of two things;
  • Summon Minions - These orbs summon Vampire Bats and Mages, kill them as they spawn.
  • Blood Wave - The orbs with a bubbling effect beneath them waves of blood across the arena, avoid standing near them and move away from the waves.
• Summon Blood Seeker - Starting at 80% health Lord Zir occasionally summons a Blood Seeker after losing a portion of his life.
  • Burst the Blood Seeker down as these can be dangerous if ignored.
• Empowered Blood Rain - Below 60% health Lord Zir rapidly flaps his wings causing the blood pools to emit projectiles which inflict Vulnerable.

Each Boss has a different loot table of Uniques and cosmetic item(s).

Unique Loot table

The items listed below have an increased chance of dropping from this Boss. You can still find items that aren't on the list, and you are not guaranteed to find a Unique every time you kill the boss.

Mythic Uniques

Basic Information

• All bosses have a chance to drop Mythic Unique items.
• These items are very powerful and very rare.

Most endgame builds use one of these items. Thankfully, all of the bosses above have a greater chance to drop them. This means you can focus on any boss that has the regular Unique item you are looking to obtain or upgrade and still have a chance at a Mythic Unique.

• Check out our Unique and Mythic Unique Guide for more details and more ways to obtain these truly Mythic items.

Cosmetic Reward

You can unlock the following exclusive cosmetic reward when you defeat Dark Master (Lord Zir).
