There are a total of three Lightning Strike probe puzzles in the Seirai island of the Inazuma region. Seirai island was introduced in Genshin Impact 2.1 update on 1st September 2021. This article shows how to solve all the Lightning Strike Probe puzzles in Seirai island. But first I will start by explaining how these puzzles work.
How Lightning Strike Probe Works
Lightning Strike probe is a device found in Inazuma, a newly introduced area in Genshin Impact 2.0 update released on 21st July 2021. The device has a compass attached to the top that points towards objects charged with electro element.
On the base of the Lightning Strike Probe, there is a protruding edge representing the direction in which the compass needs to be pointed (See the picture below). Use electro element to make the compass point in the correct direction and this will make the device glow, as shown in the second picture below. Once the device starts glowing, it will keep glowing only for a small period of time. To complete the Lightning Strike Probe puzzle, you will need to make all the devices glow simultaneously.
1) Seiraimaru Lightning Strike Probe Puzzle
There is a 3-Probe puzzle on the beach near the Seiraimaru ship. To the west of the ship, you will find an electrogranum as shown in the picture below. Get electro charge by summoning electrogranum from the plant and then activate the three probes. One of the probes is hidden behind the bushes as shown in the second and third pictures below. On completing the puzzle an exquisite chest will spawn.
2) Fort Hiraumi Lightning Strike Probe Puzzle
There is a 3-Probe puzzle on the beach north of Fort Hiraumi. You will have to activate the three probes two times to solve this puzzle. The first time you activate the three puzzles, the thunder barrier will disappear. The second time you activate the three probes, a common chest will spawn.
3) 5-Probe Puzzle
There is a 5-Probe puzzle on the beach north of Koseki Village. At the center of the five probes, you will see an electro totem (see the second picture below). Hit the totem with electro attack and Electro-Seelie will appear at its to (see the third picture below). Use the Electro-Seelie to get charged and activate the probes. When all the five probes are activated simultaneously, a precious chest will span.
