How to Summon Lord Zir in Diablo 4

Summoning Lord Zir involves navigating to a specific dungeon, collecting required materials, and activating the summoning altar. The process requires attention to location, resource gathering, and game difficulty settings to ensure a successful encounter.

Ancient’s Seat and The Darkened Way Location

Lord Zir’s lair is located within The Darkened Way dungeon, situated in the Kehjistan region east of Kyovashad. Players must enter this dungeon and descend to its lower floor to find the Ancient’s Seat, which serves as the boss’s personal chamber.

The Ancient’s Seat contains the Bloodied Altar where Lord Zir can be summoned. Access is only possible after reaching this inner part of the dungeon, requiring traversal through The Darkened Way and clearing associated enemies or obstacles. The location is a known endpoint for initiating the encounter and is distinguishable by its unique lair design.

Required Materials: Exquisite Blood

To summon Lord Zir, players need a specific quantity of Exquisite Blood, a boss material dropped from Elite monsters, Treasure Goblins, Hellborne enemies during Helltide, and various world events. On Normal difficulty, the cost is 9 Exquisite Blood, while Torment requires 27 Exquisite Blood plus an additional Stygian Stone.

Exquisite Blood is relatively common but requires farming to amass in sufficient quantity. The increase in required materials for Torment difficulty reflects the more challenging fight but rewards players with multiplied loot and stronger drops. Gathering these materials is essential before interacting with the summoning altar.

Unlocking and Using the Bloodied Altar

The Bloodied Altar is located at the end of the Ancient’s Seat chamber and functions as the summoning point for Lord Zir. To activate it, players must ensure they have all required materials in their inventory.

Once the Exquisite Blood (and Stygian Stone for Torment) are used on the Bloodied Altar, the boss encounter begins. This action consumes the materials, barring any interruption or failed summon. It is necessary to clear room around the altar to prevent interference during the summoning phase and prepare for immediate combat.

World Tier and Torment Difficulty

Lord Zir can be summoned in various World Tiers and difficulty modes, with Normal and Tormented being the primary levels for this boss. Normal difficulty is at Level 75, while Tormented Zir reaches Level 200, raising both the challenge and potential rewards.

Tormented difficulty requires additional materials but offers five times the loot and a significantly higher chance of Mythic Unique drops. Players must balance their character’s power against these difficulties, as Tormented bosses have enhanced mechanics and damage.

Managing World Tier settings accordingly allows players to control the fight’s intensity and optimize farming efficiency for desired item drops. The availability of lair keys and Spiritborn abilities may also impact strategies when preparing to summon Lord Zir.

Lord Zir Fight Strategy, Boss Mechanics, and Loot

The Lord Zir fight challenges players with a mix of shadow and physical damage attacks, environmental hazards, and waves of summoned adds. Success depends on understanding his key abilities, optimizing resistances, and efficiently managing the stagger mechanic. The loot reward chest contains unique items vital for endgame progression.

Boss Abilities and Environmental Hazards

Lord Zir combines heavy shadow damage with physical strikes. He creates blood puddles that deal continuous damage over time, urging players to stay mobile and avoid standing in them. His frontal cleave attack requires careful positioning to evade by moving to his sides or behind him.

At around 50% health, he summons blood orbs scattered throughout the arena that damage on contact. He also calls forth Elite Bloodseekers adds from 75% health, which must be cleared promptly to avoid being overwhelmed. His stagger bar mechanic temporarily stuns him when fully depleted, opening a window for heightened damage.

Recommended Preparation and Resistances

Maximizing Shadow Resistance is crucial for reducing damage from Lord Zir’s attacks. Players should prioritize equipment and buffs that boost shadow resistance, including the Elixir of Shadow Resistance II. Balancing survivability with strong single-target damage is advised, as the fight demands quick elimination of adds and steady DPS on the boss.

Playing a trench-tested build familiar to the player helps maintain control over the fight. While fire resistance is generally less important here, maintaining decent physical resistance can reduce overall incoming damage. Preparation also involves acquiring at least 12 Exquisite Blood to open the reward chest after defeat.

Reward Chest and Unique Loot Table

The reward chest unlocks with Exquisite Blood and contains a guaranteed boss-specific unique item, with subsequent unique items having a 50% chance to come from the general loot pool. Group size improves the chance for additional unique drops by 33% per member.

Notable unique items include gear like the Diadem of the Ancient Helm, Blood Artisan’s Cuirass, Esadora’s Overflowing Cameo, and Ramaladni’s Magnum Opus. Lord Zir also drops crafting items such as Pincushioned Doll and Stygian Stone, which are parts required for summoning other bosses or crafting lair keys.

Players facing a Belial Ambush after the fight gain the chance for extra loot without additional materials, including the Betrayer’s Husk needed for advanced challenges.
