With the launch of Diablo 4: Vessel of Hatred, Blizzard has introduced a long-awaited feature that hearkens back to the Diablo IV Items franchise’s roots — mercenaries. Unlike previous iterations where mercenaries were largely passive followers with minimal customization, Vessel of Hatred reimagines them as powerful, customizable allies that can complement your build and dramatically influence combat. In this guide, we’ll break down how to recruit all mercenaries, what each one offers, and how to use them effectively.

What Are Mercenaries in Diablo 4: Vessel of Hatred?
Mercenaries are NPC companions that fight alongside your character, offering both offensive and defensive support. Each mercenary has their own class-like identity, gear slots, and skill trees, making them more than just sidekicks—they're strategic assets in combat. Players can recruit different mercenaries, level them up, and equip them with loot to enhance their effectiveness.

These allies are not only useful in solo content but also provide synergy in group play, offering buffs or crowd control options that fill in gaps in team composition.

How to Unlock Mercenaries
Mercenaries become available during the Vessel of Hatred campaign after you complete the first major story arc in Nahantu, the new jungle-themed region introduced in the expansion. Here’s the general progression:

Complete the "Shadows of the Wild" questline in Nahantu.

Defeat the region’s first major boss, tied to the Vessel of Hatred's lore.

Visit the Mercenary Hall in the capital city of Nahantu (called Uzir).

Speak to Captain Nyra, who manages the mercenary guild.

From this point, you’ll gain access to the Mercenary Interface, where you can recruit and manage mercenaries.
