Story
A nagamaki sword designed by one of Tatarasuna's inspectors.
It is said that the diagram is as simple and upright as that inspector was.
For a long time, before the introduction of the outlander technology that helped build the Mikage Furnace,
Tatarasuna smelted iron using the traditional "Tatara Metalworking Method."
After Mikoshi Nagamasa became the inspector, he was for a time obsessed with the grim loveliness of steel.
He thus consulted the similarly inclined Armory Officer Miyazaki for advice,
With the result being this tough and simple sword, the Daitatara Nagamasa.
Although he was only the foster son of the Mikoshi Clan, and although his foster mother had stained the reputation of the Mikoshi,
And even though Mikoshi's only legitimate heir, Doukei, abandoned him and disappeared,
His self-admitted stupidity and loyalty led him to cherish the Mikoshi name all the more.
He strove to enter the government and got rid of the family's bad reputation with his diligence and righteousness.
When his yoriki Katsuragi was connected with but a single trace of misconduct, he had him executed without mercy.
Ever since then, the name of the sword and his title were changed forever.
Trivia
-The Amethyst series of weapons is the first to require completion of quests in order to be unlocked for crafting.
-The item called Rather Aged Notes references the Katsuragkiri Nagamasa with its text.
FAQs
How can I forge Katsuragikiri Nagamasa?
The Inazuman craftable weapons are unique in that they require the completion of certain questlines in order to be accessible for crafting. These quests are accessible at any time once you have completed the introductory parts of the Archon Quest. In Katsuragikiri Nagamasa’s case, completing the seven days long “Tatara Tales” World Quest chain is necessary to unlock its blueprints.
Who are some of the best users of Katsuragikiri Nagamasa?
The Inazuma craftable weapons have a general focus in Energy Recharge manipulation in order to either boost damage outright or quickly replenish energy for more frequent bursting. Sayu is a high end user of it thanks to her powerful Elemental Skill as well as making great use of the Energy Recharge to be bursting more often.
Is Katsuragikiri Nagamasa good?
Between its Energy Recharge substat on top of its passive that generates more Energy particles overtime, there are very few other options in Genshin Impact that are better for particle generation than Katsuragikiri Nagamasa, making it a fine choice for Elemental Burst centric characters who to maximize their uptime.
Final Thoughts
Katsuragikiri Nagamasa’s greatest strength is its availability as a crafted weapon, even if it is one of the few that require prerequisite quests to be completed in order to do so. It is outright one of the strongest options in the game in terms of maximizing energy gain to be bursting as often as possible, so if this is what you are gearing up a character to do, it makes it an excellent choice for the job!
