In Genshin Impact, players can get the blueprint for Katsuragikiri Nagamasa claymore from a Luxurious Chest found inside a locked cave room in the Tatarasuna area, on Kannazuka Island. However, to open the locked cave room, players need three keys. When you get any of the required keys while exploring the same Tatarasuna area, you get the message “Key to Some Place” and guess what?, the someplace is none other than the locked room where you can find the Katsuragikiri Nagamasa claymore diagram.
Finding all the keys without knowing their location will take a lot of time. And, there is also a chance that you might not find it on your own. In the wake of that, we have prepared a handy guide that talks about all “Key to Some Place” locations.
All “Key to Some Place” Locations in Genshin Impact
As we mentioned earlier, players can find all three keys in Tatarasuna itself. We have marked the location of the locked cave and the three keys required to open the iron door in the above Genshin Impact map.
To access the above location, you have to complete the first part of Tatara Tales’ world quest. Only then, you can access the furnace area where you will find the keys to some place.
The star icon denotes the key location and the mission icon, one with the exclamation mark, denotes the chest location.
Once you have all three keys, go to the chest location. Open the iron door, defeat three ruin sentinels, and at last open the Luxurious chest to get Katsuragikiri Nagamasa blueprint and other rewards.
