Location of the Arsenal
There is an Arsenal in the central part of Tatarasuna near the river (Check the image below for location). You can obtain 30 Primogen, 3 Hero’s Wit, 30000 Mora and Katsuragikiri Nagamasa Diagram from the Arsenal. But the Arsenal is locked and 3 Key to Some Place are required to unlock the Arsenal. This guide will show you the location of all the three Keys to some place in Genshin Impact 2.0.
Key to Some Place #1
Key to Some Place #1 is in the northeast part of Tatarasuna (check the image below for 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 on to 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 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 from the cliff and can easily glide to the common chest.
