There are a handful of legendary weapons that you can find when playing Once Human, but tracking them down can be a challenge. There’s the Fabled Masamune katana that many melee-focused players will want to get their hands on, but it doesn’t appear very often.

You’ll want to focus on finding it in a specific location. The Fabled Masamune katana doesn’t drop in every location, and even if you’re in the right place, chances are you won’t be able to get it. It all comes down to replaying dungeons and playing through the same content in Once Human, hoping you’ll be lucky enough to find these weapons and add them to your collection.

The Fabled Masamune katana can be dropped while exploring the Securement Silo-Theta dungeon, which can be found in the Red Sands area. The Red Sands is one of the last regions you can unlock in Once Human, meaning you'll have to complete a large portion of the main story missions to reach it. You'll gain access to the Red Sands after defeating the Shadow Hound at the Monolith of Thirst in the Chalk Peak area. You can also expect to find high-end loot, like the Expanded Rifle Magazine or crystals for your Rare Crystal Sets.

You don’t want to go straight to the Securement Silo-Theta dungeon after unlocking Red Sands. It’s a level 45 dungeon, and you can farm it better by making sure you’re either leveled up or regularly prepared to fight level 45 enemies. These enemies can easily overwhelm you, so you’ll want to get through most of the strongholds scattered throughout Red Sands in Once Human before you start this adventure.
