Boss Mechanics and Strategy
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.
- 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 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 release 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.
Useful Tips!
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.

Loot Tables and Rewards
Each Boss has a different loot table of Uniques and cosmetic item(s), with a chance of dropping the highly sought-after Mythic Unique items. How loot is distributed and rewarded has been changed with Season 8, and is now tied to using the Boss Lair Keys.
To receive loot, you must use 12x Exquisite Blood to open the Hoard. The Hoard has 2 Unique items in Torment 1, granting one extra for each Torment difficulty increase, and 2 extra for Torment 4. You are guaranteed one boss-specific Unique when you open a Hoard. You can increase this by 1 for doing Torment 3 or higher, and another 1 for being in a party. While in a party, you have a 33% chance of getting 1 additional class-specific item per party member.
New for Season 8 is the General Unique Pool. On average, 50% of the non-guaranteed drops are now from the General Unique pool, and the other 50% are boss-specific Uniques.
