The Missing Brother contract in The Witcher 3: Wild Hunt is one of the most intense monster-hunting quests available in the Velen region. Players take on the role of Geralt of Rivia to investigate the disappearance of Mikula's brother, Mikkel, who vanished near an abandoned mine. This contract presents a formidable challenge that tests your prep work, tracking skills, and combat proficiency against a terrifying subterranean beast.
Starting the Quest and Investigating the Inn
To begin the contract, head to the Inn at the Crossroads in Velen and check the local notice board. Speak with Bruno inside the tavern to negotiate your reward for finding his missing brother Mikkel. Bruno explains that Mikkel led a group of women to hide in an old mine, but no one has returned since.
Tracking the Footsteps inside the Mine
Make your way to the mine's entrance situated northwest of the inn and prepare your Witcher Senses to track the path. As you navigate the dark tunnels, you will discover bloodstains, abandoned supplies, and signs of a severe struggle. Diving into flooded underwater caverns will reveal the tragic fate of the refugees who sought shelter here.
Preparing for the Harrisi Boss Fight
At the deepest part of the cavern system, Geralt confronts Harrisi, a dangerous unique Venomous Arachasae. Before engaging in combat, coat your silver sword with Insectoid Oil and equip Golden Oriole potions to negate deadly poison attacks. Utilizing the Igni sign against Harrisi and her spiderlings will help manage crowd control effectively during the battle.
Confronting Bruno for Your Reward
Once Harrisi is slain, examine Mikkel's body to confirm his fate and gather the Arachasae Trophy as proof. Return to the Inn at the Crossroads to report your findings to Bruno. Depending on your dialogue choices, you can either collect a reduced payment or use Axii persuasion to demand your full promised reward.
