Corundin in Genshin Impact - a kitchen ingredient originating from Natlan due to connection with phlogiston. The gemstone is both a mineral and a flower at the same time, since it is the fruit of a crystalline tree. According to legends, once its fruits were disguised as jewelry by Waxaklahun Uba Kan in order to deceive the greedy dragon who took up residence on the sacred mountain.
In the guide we will tell you how to find corundine in Natlan, whether you can buy it and what kind of food it will be useful for preparing. The Corundin map, along with the route indicated on it, will help you quickly collect the required amount of resource.
What does Corundin look like?
Corundin looks like a bluish open flower bud, from which yellow crystals extend instead of stamens. They are surrounded by feathery leaves, blue-red-white from the base to the tips. The plant is supported by a curved, strong brown stem that grows directly from the phlogiston.
Preparing to farm Corundin
To simplify the path along the Corundin farming route, it is worth preparing a group in advance by placing characters in it to help with the exploration of the world. Some dishes will also come in handy if you find yourself in various situations.

Where to Find Corundine in Genshin Impact: Farming Routes
Corundin is found in areas with liquid phlogiston, which are especially dangerous due to their similarity to lava. Typically, such areas can be found underground in the Natlan region. Each bush grows two fruits, and a total of 30 resource units.
Route 1: Tepeacaque slope
Complete the quest "Prepared for trouble"to open the passage to the Warm Cave and fully explore it. This route for collecting corundine is quite difficult, since here you need to go down to the lower level of the cave and overcome lava flows. In total, you can get 4 fruits.
Teleport to the underground point of the Tequemekán Valley and glide to the center of the cave, where you can take the form of a Yumkasaurus. Use its abilities to pull yourself up to the floating Dendro symbols on the right and reach the deep pit.
Dive into the tunnel on the left and continue moving through the dots to the pool of liquid phlogiston.
When the Dendro symbols are finished, jump to the safe earthen path and follow it to a small threshold. From there, follow straight ahead and you will get to a lava waterfall, at the foot of which grow bushes with corundines.
Route 2: Waters of Ameyalco
Continue farming for Corundine on the lower level in the waters of Ameyalco, which are located east of the Folk of the Springs tribe. Just by the underground lava river that opens up during the side quest "The past cannot be traced", can be collected 26 units of materials.
The first bush where the corundine is located grows below the teleporter.
From the portal, turn in the opposite direction and check the foot of the river, where there will be two more fruits.
Go down to the right and take the fruits located on a small ledge of land.
Go to the south of the dungeon along the river of lava and collect resources from the bush on the island by possessing the nearby Colohosaurus.
Swim closer to the waterfall at the other end of the pool and pick up two more fruits.
Use the current funnel to jump to the level above and examine the stream of phlogiston flowing down.
In the same lava pool, pick up more fruits at the other end.
Quickly ascend to the second part of the underground location along the spiritual path. The next place to look for corundine is surrounded by aggressive penguins.
Swim along the river to the cascading waterfall to collect two more fruits along the shore.
Reach a dead end where there is a strong lava flow - there you will find a bush with materials and a timed challenge.
Return to the start of the long pool and this time turn left towards the rise, along the way you will notice the plant you need.
Climb up the dirt hill and check the small cave on the left, where there will be another one next to the corundum. Pyrocule.
The last bush is located near the waterfall on a small rock immersed in lava.
Route 3: Phlogiston Extraction Research Center
You can get to the underground location by passing by Fatui's lair, located to the east of the Temple of the Ancestors. This area is associated with a quest keys with notches. In total, there are growing along the lava river 12 corundines.
The first two bushes are hidden at the entrance to the experimental area, in a small pool of phlogiston to the left of the iron pipes.
Go down to the central platform guarded by two Fatui and collect more fruits from the branch near the rise.
Look at the nearest pool to the right of the previous gathering place, on either side of which there are two more bushes growing.
Walk a little north of the central area and you will notice a few more Corundins.
Where to buy Corundin
Since Corundine is a common kitchen resource, it's sold by a Natlan merchant with a specialized inventory. To do this, head to the Children of Echoes tribe from the underground teleporter, following the upper path.
A little before you reach the Obsidian Pillar, you'll run into a girl named Imish, who'll sell you ten units for 2400 Mora (240 Mora each). The shop refreshes once a week.
How to get a resource for free
There are no NPCs or activities in the game that would give out materials for free.
How to Grow Corundine in the Serenity Teapot
Another place to extract the resource is Serenity teapot. Place the required field in the house and place several seeds on it so that they will grow into jewelry over time. You can buy them from Pukhlyash on the page "Flora and fauna of the monastery", and get it in the process of collecting a flower in the open world using Chest of seeds.
What is Corundin used for?
Corundine is used to prepare 4⭐ dishes "Shimmering Gems", which buffs allies. Its recipe requires 1 Cacahuatl, 1 Corundine, 1 cereal fruit and 1 mint.

1. Kachina will not show the location of Corundin on the map.
2. Corundin can be purchased from a female merchant in Natlan. Imish in the settlement Children of EchoIt's located next to the Muhuru Gems shop (under the level with the Obsidian Reputation Totem Pole).
3. Imish in the Children of Echo settlement sells 10 corundines for 240 mora each. The inventory is refreshed every three days.
It is also used for "Corundine Bait", 1 Corundine and 1 Cereal, purchased from the Natlan Fishing Association from Oroluk.
Which NPC gives it for free?
By the way, there's an inaccuracy in the article. Searching for rarities like kachina and other gemstones won't help you find corundum, as it's not considered a rarity.
Could you tell me more about route 3 and how to get there? I can't find Fatui (and I don't even know where to get there).
If only there was a screenshot of where exactly to go.
I barely found it, but a screenshot of the Research Center level: Passage and an arrow indicating the start on the terrain (without a view of the dungeon) would be a good reference point. There's a very long passage there, with a lot of Fatui, and it's best to approach it from the northeast of the Ancestral Temple, rather than from the east.
