Lord Zir is one of the most efficient and rewarding pinnacle bosses in Diablo 4, especially in the Season of the Infernal Hordes. With his plentiful item drops, including Mythic Uniques and build-enabling base Uniques, he has become a popular target for endgame players looking to farm high-quality loot. While the fight itself may seem intense, Lord Zir's fairly straightforward mechanics make him an excellent choice for farming, particularly if you're prepared for his attacks and patterns. Below is a detailed guide on how to summon, defeat, and farm Lord Zir effectively.
How to Summon Lord Zir
To summon Lord Zir, you will need to venture into the Darkened Way Dungeon in Kehjistan, which is located east of Kyovashad. The process to summon him requires gathering the right materials:
Location: The Darkened Way Dungeon
Once inside, head to the lower floor and enter the Ancient's Seat lair.
Continue through the lair until you reach Lord Zir's summoning altar.
Materials Needed:
Exquisite Blood: A common drop from Elite monsters, Treasure Goblins, and Hellborne enemies during Helltide, and world events.
Stygian Stone: To summon the Tormented version of Lord Zir (Level 200 variant). This is more difficult to acquire and can be found in higher tiers of The Pit and the Infernal Hordes.
For Tormented Zir:
You will need three times the amount of Exquisite Blood and a Stygian Stone for the Level 200 variant.
Lord Zir Boss Fight Mechanics
The Lord Zir fight is challenging but manageable with the right preparation. Below is an overview of his key mechanics and how to approach the battle.
Phase 1: The Initial Attack
Melee Attacks: Lord Zir primarily uses melee slashes with his claws. These are typically weak unless empowered with blood.
Blood-Empowered Claws: If Lord Zir starts to glow with blood energy and raises his claws, dodge immediately. The attack will inflict a debuff in Tormented difficulty that increases incoming damage-multiple stacks of this debuff can quickly overwhelm most builds.
Blood Orbs and Pools
Blood Orbs: Every 20% of Lord Zir's health will cause a Blood Orb to spawn in the arena. The orbs function like autonomous turrets, periodically sending out blood waves. The waves don't deal much damage individually, but you'll need to dodge them to avoid being overwhelmed by additional mechanics.
Blood Pools: These will slow down your movement when you step in them. Try to avoid them to keep your mobility high. They also make it harder to dodge other attacks, especially when there are multiple pools on the ground.
Phase 2: 50% Health Threshold
Once Lord Zir reaches 50% HP, his attack pattern will change:
AoE Attacks: Zir will begin performing multiple AoE attacks, making it harder to read the battlefield.
Rectangular AoE Attack: Lord Zir will channel a massive rectangular AoE, dealing heavy damage. Dodge or circle him to avoid this attack.
Blood Pulses: When Zir pulses with blood, all blood pools on the ground will spawn player-seeking projectiles, inflicting Vulnerable status on hit. This is one of the more dangerous mechanics, as it forces you to be extra cautious.
Phase 3: Last 20% of Health
Increased Chaos: In the final stretch, the battlefield becomes very chaotic, as the blood orbs and pools fill the arena. The seeking from the pools will also make dodging significantly harder.
Kill Speed: The key to surviving this phase is increased damage output. If your build can melt Zir's HP quickly, this phase becomes much more manageable.
Tips for Defeating Lord Zir
Upgrade Damage: If you find the final phase difficult, consider upgrading your damaged output. Having a high DPS will allow you to kill him faster, minimizing the number of mechanics you need to deal with in the later stages.
Positioning: Stay mobile throughout the fight, especially when Zir starts to spawn blood pools. Position yourself so you can avoid the pools while still dealing damage.
Dodge the Debuffs: Lord Zir's blood-empowered claws inflict a dangerous debuff that increases the damage you take. Avoid getting hit by these, as multiple stacks can quickly overwhelm your defenses.
Manage AoE Damage: The rectangular AoE attack can be very punishing, so be sure to dodge and circle the boss. Keeping your distance can help you manage this mechanic better.
Use Defensive Skills: Have defensive cooldowns ready to survive when the blood projectiles start to track you down. Utilize crowd control abilities to buy time if needed.
Lord Zir's Drop Tables
Lord Zir's drops include a wide variety of valuable items, making him a great farm target. Here's what you can expect:
Mythic Uniques: These are rare, endgame items with unique affixes that can dramatically improve your build.
Base Uniques: These build-enabling Uniques are tailored to many class builds and can offer powerful bonuses.
Legendary Items: High-value Legendary gear drops frequently in his fights, especially for the Tormented variant.
Exquisite Blood: A common drop during the fight, which is used to summon Lord Zir or other pinnacle bosses.
