How to unlock Mercenary Subo in Diablo IV: Vessel Of Hatred

Diablo 4: Vessel of Hatred introduces the Mercenary system, which allows you to fight alongside four different NPCs, each with their own build. You unlock your first mercenary through the Vessel of Hatred campaign, but the next three must be unlocked through specific quests.

Subo, the Bounty Hunter, has several skills that focus on trapping enemies and dealing them high damage. Below we'll look at how to start and complete the A Feather on the Scale quest to unlock Suba as a Mercenary companion.

You can start this task soon after first reaching the Lair and unlocking Raheer as a mercenary.

After you've done that, you're good to go “Feather in the Scales” interacting with A muddy letter near the hideout in the lair.

First, talk to Raheir and show him the helmet that came with the letter, then head to Toxic Swamps in Hawezar and start searching for Subo. You can use Vyeresz Waypoint if you have it unlocked, otherwise Air crossing point is the second closest.

Either way, head to the Toxic Fens. When you get close enough to a quest objective, it changes to an area marker; look here for Subo, who should be there in the upper right part of the areato the right of near the statue of Lilith.

Talk to Subo to learn about his plan, then enter Smuggler's bunker immediately left. Inside, find Subo and talk to him, then defend him from him three waves of bandits as he interrogates his captive. Talk to Subo again and then head to Altar battered by the wind for the next part of the quest.

From the Smuggler's Bunker, go to west towards the Wind Altarthen talk to Subo and hear his plan. Then head inside the Windswept Altar.

In this dungeon, fend off groups of enemy Bandits as you progress into the depths. As dungeons go, this one is fairly simple. When you reach the deepest point, approach the boss and watch the cutscene.

Now fight the final boss of the Windswept Altar, Avashtha, the Malformed Serpent. This enemy shoots spiral balls of poison and creates bloody clones of himself which cause damage in the lines on their front. Watch out for danger indicators and use yours evasion and movement skills to avoid damage.

Once the boss is dead, return to the underground entrancethen talk to Subo again to complete the quest. Now that you return to the Lairyou will have the option to take Subo with you as your mercenary.
