This quest is level 25 but you are able to complete it much lower. I actually completed the quest at level 13 on normal difficulty. You unlock the quest by speaking with the Blacksmith in Novigrad, he is also the Master Blacksmith for those looking for better weapons. Speak with him at the Blacksmith’s and accept his request. You’ll need to head to the docks at night to meet with a contact. During the conversation ask to negotiate then stay at 25 both times. When they leave tell them it’s fine, the deal is off.
Following that a group of bandits attack. Just try to avoid any damage and use your ranged abilities and weapons while the NPC with you kills them off. Return to the Blacksmiths. He will then ask you to find him a bodyguard to protect him when you’re gone. Follow the objective marker until you meet Sukrus, you’ll need to defeat him in a fist fight if you want him to hear you out. Despite the huge level difference, you can take him down easily.
You’re then asked to settle a debt before Sukrus will help you. Go the docks and speak with the Trader. If you haven’t already I suggest leveling Axii as it allows you to convince him to pay the debt without further trouble. Return to Hattori and you’ll learn of the next stage of this quest. He asks you to steal some equipment from Van Hoorn’s Warehouse after dark, Sukrus and some of his friends will provide aid. Follow the objective marker to the Van Hoorn’s Warehouse, and then speak to Sukrus outside when it’s in the darker hours of the day. After speaking with Sukrus and heading towards the objective, a couple of drunks will block your way. Again, use Axii to convince them to go home and there’s no problem.
When you reach the entrance to the warehouse you’ll again be given a conversational choice. Using the Axii option to force entry makes it simple. Head inside and use your Witcher Sense to mark the 3 crates. When you exit you’re given a timed conversation choice to fight or wait, I chose fight. Again, I was only level 13 doing this so don’t be concerned if they are 5-10 levels higher. Simply use your AI companions as the meat shields and throw in damage when you can. Be sure to use your weakening sign, Thunder potion and rear attacks for maximum effects. After the fight you finally complete the quest, unlocking the use of the Master Blacksmith. Speak with him afterwards and request your sword, then simply Meditate for 24 hours and collect it.
