Claymore: Katsugakiri Nagamasa

You will find Blueprint for ‘Katsugakiri Nagamasa‘ claymore inside a Luxurious chest in the Arsenal, which is in the central part of Tatarasuna near the river (Check the image below for location). The Arsenal is locked and 3 Keys to Some Place are required to unlock the Arsenal. The location of the keys is described below.

Key to Some Place #1

Key to Some Place #1 is in the northeast part of Tatarasuna (check the image below for the exact location). The common chest containing the key is in the broken building inside the purple-colored dome (shield). You’ll need electro to cross the shield (enter the dome). There is an electrogranum plant nearby and is pretty hard to miss. Cross the shield –> go downstairs –> take a sharp left and jump down onto the wooden platform –> enter the narrow space to get to the common chest.

Key to Some Place #2

Key to Some Place #2 is in the southeast part of Tatarasuna (check the image below for the exact location). Move north from the teleportation waypoint and jump down from the ledge. Glide down to reach the broken wooden platform with the common chest (containing Key to Some Place #2). This wooden platform is located somewhere above the Arsenal gate.

Key to Some Place #3

Key to Some Place #3 is in the central part of Tatarasuna near the Mikage Furnace (check the image below for the exact location). The common chest containing the key is on the roof of a hut in the Mikage Furnace area. It’s better if you approach the Mikage Furnace from the cliff on its western side. You can jump off the cliff and can easily glide to the common chest.

Once you have the three ‘Keys to Some Place’, open the arsenal gate and get the ‘Katsugakiri Nagamasa‘ blueprint from the Luxurious chest inside it. Once you have the blueprint, go to a blacksmith and forge the sword for 1 Northlander Claymore Billet, 50 Amethyst Lump, and 50 White iron Chunk for 500 Moras.

Bow: Hamayumi

You will get the blueprint for Hamayumi Bow from a common chest in Takashi’s Conch House which is on the northern beach in Tatarasuna at the location as shown in the picture below.

On the beach near the Conch House, you will find some shiny objects and there is a chance that you will find Mysterious Conch. You will find around 4-5 Mysterious conch each day. You will be needing only three every day.

Once you have three conches, go and talk to Takashi in the conch house. You can give him three conches and in return, he will allow you to open one of the three common chests behind him in the conch house. There is a small chance that from one of the common chests you might get a blueprint for Hamayumi Bow. You can do this only once every day and you might have to do it for 10-15 days before you get the blueprint.

Once you have the blueprint, go to a blacksmith and forge the sword for 1 Northlander Bow Billet, 50 Amethyst Lump, and 50 White iron Chunk for 500 Moras.
