How To Summon Lord Zir

Lord Zir is found inThe Darkened Way dungeon in Kehjistan, located east of Kyovashad.Once inside, head to the lower floor and enter the Ancient’s Seat lair instance. This is Lord Zir’s personal chamber. Head to the end of the lair to find Zir’s summoning altar.

As with all pinnacle bosses in Diablo 4, you’ll need certain materials to summon this boss.

Diablo 4 Lord Zir Summoning Tormented

Summoning this boss requiresExquisite Blood, a fairly common boss material that drops from Elite monsters, Treasure Goblins,Hellborne enemies within Helltide, and world events. If you want to take onTormented Zir, a Level 200 variant, you’ll need three times the Exquisite Blood and a spare Stygian Stone. You can find Stygian Stones in higher tiers of the Pit and the Infernal Hordes.

Tormented bosses drop quintuple the items of a standard pinnacle boss, making them more efficient to farm if you can handle the added difficulty.If you have Stygian Stones, this is always worth doing.

Diablo 4 Lord Zir Blood Pools

Lord Zir Boss Guide

Lord Zir tends to fight within melee range, but the arena will get progressively more chaotic as the fight continues.When the fight starts, Zir will attempt to hit you with his claws.The normal slash is fairly weak, but if you see Zir empower his hands with blood, dodge out of the way.The blood slash attack inflicts a debuff on Tormented difficulty, greatly increasing all incoming damage. Most builds can’t survive past three stacks.

Every fifth of the boss' HP you remove will spawn a blood orb in the arena, an autonomous turret that spawns blood waves periodically. It doesn’t deal much damage on its own, but the waves add another mechanic you need to avoid. Additionally,Zir will start to spawn blood pools in the arena.These will greatly slow your character’s movement speed. Try to avoid them when possible.

At roughly 50% HP, Lord Zir will start to perform multiple AoE attacks that greatly reduce the visual clarity of the fight.He will start to channel a rectangular AoE attack that deals massive damage.Circle around the boss to avoid it. If Lord Zir starts to pulse with blood, every blood pool on the ground will spawn player-seeking projectiles, inflicting Vulnerable on hit.

This fight gets fairly chaotic at this stage, sotry your best to stagger or outright kill Lord Zir before too many projectile spawn.The last 20% of his HP is the toughest, as you’ll need to juggle multiple blood orbs and the puddles on the ground. If you’re struggling to kill Zir, we highly recommend upgrading your character’s damage before you attempt this fight again. The second half of this fight is much easier if you’re able to melt the boss' HP.
