Orobashi's Legacy Part 3 Genshin's Impact World Mission - Pearl and Watchstone

With Part 2 hopefully completed (although Part 3 is not required), we can now grab the Jakotsu Mine Pearl and the Warding Stone. For this guide, we will start by solving the Sacred Stone Puzzle first, which will give us access to the Ward. Next, we will find the Pearl and the Stone of protection that need to be placed in the Department we have unlocked.

To get started, you'll need to teleport to the teleporter which is located east of Maguu Kenki, which sits atop a cliff overlooking the Jakotsu Mine. Once there, slide down the hill and over the large well, and you'll find a sacred stone mound. Rotate this mound to face the Tunderbearer Mirror east next to a couple of electric compass puzzles.

Now, you need to go to the Thunderbearer mirror you aimed at, rotate it to the west and tilt it to aim down. This should line it up with the mirror just below it.

From here, point this lower mirror north-west, towards the mirror resting on the axes of the bony cliff seen below.

Now at the bone cliff mirror, aim directly south and tilt this mirror down, so that it hits the mirror seen below. This is the mirror more or less under the sacred stone mound.

Now rotate the next mirror so that it faces east, at the Thunderbringer's Mirror with a mirror floating right above it.

Almost done! Point this Thunderbringer Mirror at the only mirror we haven't adjusted yet. Do this by aiming this mirror to the northeast, so that it redirects the shot through the mine.

And in the end, point the final mirror south and tilt it down so that it redirects the shot into the great barrier (in the image below, the search is complete and the barrier has already been destroyed).

Now, once you hit the Sacred Stone Mound, a cutscene will trigger and the great barrier around the Ward will be destroyed! With the Ward now available, you can investigate it and use elemental vision to find the Warding Stone and Pearl for the Jakotsu Mine.

To get the Warding Stone, you will need to go to the left of the shrine and climb the rocks that lead to a cave. When you enter the cave, you will find Thunder Sakura Boughs and collecting their Electrograna will allow you to climb onto the ledge shown in the image below. On this ledge is a small electrical barrier that you can cross as long as you still have the Electrogran on you. In this barrier you will find the "protective stone of the rock pillar of the Jakotsu mine".

To get the Pearl, you'll need to go back to the Ward and, instead of left, go right (again, your elemental vision will guide you roughly along this path). The Pearl will go through this branch of the cave and will require some combat, so be prepared to fight mainly hydro enemies, both Slime and Abyss Mages (one will be Electro). Eventually, you will come to the end of the cave, as shown below. This is where the Abyss Wizards will give you a hard time. Once defeated, use an Electrograna to access the Electro barrier and jump up to grab the "Jakotsu Mine Rock Pillar Pearl". This is in the air, so you may need to use a character with upward mobility such as Venti, Geo Traveler, or Keqing. Maybe you could even use Mondstadt's Wind Catcher gadget.

With both the Warding Stone and the Pearl in your possession, return to the Ward and send these two items to complete Part 3 of Orobashi's Legacy.
