Secret Fire Thief Island is a hidden location in Natlanin Genshin Impact that doesn't show up on the map. It can be reached with the help of some Cryo characters who can create bridges, or with Furina's Elemental Skill, but with the new Pyro Region mechanic, it's easy enough to possess a Koholazawara to find this island hiding at the edge of the map.
All Firethief's Secret Island Challenges in Natlan
Where to Find the Island
The secret island of the Fire Thief is located in the corner of the map in the desert area. Swim to it in the form of a Koholazvar or walk along thin land isthmuses. An unpleasant surprise will be waiting for us right at the teleport point: a rainbow beam that attacks with short periods and the achievement “Only training grounds left?”, when you activate the teleporter on the island. In order to deactivate the beam, you just need to get closer to its core. By doing this with the device at the teleporter, we activate one of the challenges of this island.
First Challenge
Unlocked after deactivating the Rainbow Beam. Use the Soul Beacon to possess a Yumkazawar and use the Coiled Grass Seals to reach another Rainbow Beam and deactivate it. After that, another weapon and Seals leading to it will appear.
We jump to the core to close it and activate the last beam. We get to the rocks where it is located and deactivate it. A Rainbow Inscription appears in its place, touch it. We watch a short cutscene and get a rich chest.
Note: All the challenges on the island have no time limit, which makes them easier to complete.
Second Challenge
Located just south of the teleporter, on a small island.
Turn into a coholasaurus and activate the totem. The Rainbow Beam will appear again, which you need to swim to as quickly as possible.
We turn it off and see the second one, but the path to it is blocked by wind currents, so you can cheat and get to it along the mountain.
Note: at the altars you can replenish phlogiston stamina and restore the health of the saurian.
The third rainbow beam is hidden between the rocks, it will not be difficult to get to it from the previous beam. Carefully swim to it, hiding from the incinerating rays behind the rocks and turn it off. Another Rainbow Inscription will appear between the rocks. Again, watch the cutscene with the lit stripes on the mountain and get a rich chest.
The Third Challenge
Located on the opposite side of the island from the challenge with the Koholasaurus. We possess the Tepetlisaur to turn off another beam, then jump into the molten crack, through which, under a hail of Rainbow Beams, we get to the top of the mountain, where the Rainbow Inscription is.
Touch it to turn off all the beams and get a rich chest, as well as activate the last test and the third gold strip on the rock.
The Fourth Test
This is a combat challenge, it will only become available once the other three are completed. After activating the monument, a dendro vaiob will appear, and when we deal with it, two more vaiobs will come – geo and hydro, they also need to be defeated.
After this, the fourth strip on the mountain will shine gold, and we will receive a luxurious chest with 40 primogems, 30,000 mora, 2 Hero Experience books and 3 pieces of magic enhancement ore.
Once all the challenges are completed, the island will appear on the map.
