Masamune is a unit in NieR: Automata
A blacksmith in the forest kingdom. His teacher was a master craftsman, known for improving the 8 legendary weapons of Virtue and Cruelty. he separated himself from the network due to an internal malfunction, so he is no longer hostile towards androids. He loves weapons more than anything, and as proof of your respect for weapons, he grants you the weapon his teacher honed.
- Unlike the other weapon vendors, Masamune is able to upgrade your Weapons to level 4 (provided you have the materials).
- He can be located by transporting to the Forest Castle: Royal Chamber, heading right, toward the bridge, and jumping to the floor directly below. Proceed to walk to the left until you encounter a cube shaped crate. Move of the crate to the right by interacting with it and walking backwards. Then simply jump over the crate to reveal the blacksmiths hidden workshop.
- After upgrading any weapon to level 4, he will reward you with the weapon Cruel Lament.
