How to get the Inazuman craftable Claymore blueprint in Genshin Impact

Genshin Impact released a whole set of new forgeable weapons in Version 2.0.

The new set is named the Amethyst series in conjunction with one crucial material for all the forgeable weapons, the Amethyst Lump. Players can only forge each weapon in this series after collecting the blueprints for the respective weapons.

Katsuragikiri Nagamasa is the new forgeable claymore in the Amethyst series. The diagram for this claymore is inside a Luxurious Chest behind a locked Arsenal gate in Tatarasuna. Here's how Genshin Impact players can unlock the Arsenal gate and obtain Katsuragikiri Nagamasa's blueprint.

Genshin Impact players can obtain Katsuragikiri Nagamasa's blueprint by collecting a Luxurious Chest inside a locked Arsenal gate. This gate is located in the central part of Tatarasuna beside the river.

Following the directions on the map above, players can start by teleporting to the teleport waypoint of the southern end in Tatarasuna. Then, glide down towards the central part of Tatarasuna. From the center part, turn southwest, and players can see the Arsenal gate.

Players can unlock the Arsenal gate by collecting three 'Key to Some Place' around Tatarasuna. All the keys are placed inside a Common Chest. Genshin Impact players can discover the keys' location below.

For the first key, players can teleport to the Statue of the Seven in Kannazuka. Then, head southwest until they can see a barrier surrounding a broken tower. The Common Chest containing the key is on the second floor of the ruined building.

Genshin Impact players need to summon an Electrogranum from a nearby Thunder Sakura Bough to enter the barrier safely. Players can enter the barrier even with a low-level Electrogranum (Level 1 of Sacred Sakura Tree).

Key to Some Place #2

Genshin Impact players can collect the last 'Key to Some Place' on top of a roof in the center of Tatarasuna. For the easiest route, players can glide down from the teleport waypoint at the southern end of Tatarasuna to the houses in the central part.

Once Genshin Impact players have collected all three 'Key to Some Place,' they can head to the Arsenal gate to unlock it. The Luxurious Chest will be automatically unsealed once players open the gate.

Note that if players approach the chest, three enemies will spawn. The enemies are Ruin Cruser, Ruin Scout, and Ruin Defender. It is recommended for players to defeat their enemies first before opening the Luxurious Chest.
