There are several kinds of fish in Genshin Impact, and Golden Koi is one of them. Travelers need 20 Golden Koi, 20 Rusty Koi, and six Raimei Angelfish to get the new Polearm, "The Catch." This Polearm is great for characters that rely on their Elemental Burst, and it is also the best F2P weapon for Raiden Shogun in Genshin Impact.
"The Catch" is available to purchase from Kujirai Momiji in Inazuma, along with the Refinement Materials for the weapon. Because the fish has a pretty long respawn time, Genshin Impact players should start fishing as soon as possible.
Updated on December 17, 2021, by Scott Vengel: Genshin Impact still manages to make incredible progress, as they introduce more features in their version 2.3 update. Just as the Arataki Itto banner is being released, players are being introduced to new weapons, characters that boost the abilities of same-element teams (the Genshin Impact community isn't calling version 2.3 the "Geo update" for nothing), as well as a new occasional two banner system for character reruns. Nonetheless, players are also looking forward to expansion on previously introduced features, like the Fishing System, so this article will be updated to include more clarity for players looking to catch the Golden Koi.
Golden Koi Locations
Each species in Genshin Impact appears at a different spot and they also have their own spawn time. Some of them appear during the day while some others appear at night; the Golden Koi can be found at any time during the day. As for Golden Koi, these are the places player will find them in. Players should also be aware that Golden Koi in any one fishing location will take three days to respawn, so it may be necessary to fish at more than one location.
Stormbearer Mountains
Stormbearer Mountains is the only place in Mondstadt that contains Golden Koi. The fishing spot is easily accessible. Genshin Impact travelers simply have to walk northeast of the Teleport Waypoint. Additionally, because of its close distance to the Teleport Waypoint, this is also one of the quickest spots to get to for players looking to catch Golden Koi as soon as possible.
West of Wangshu Inn
Liyue has the most spots for Golden Koi. The first one is located west of Wangshu Inn. Players can either glide from the inn or use the Teleport Waypoint northwest of the angling location.
West of Mingyun Village
The next Golden Koi spot in Liyue is near the broken bridge that connects Guili Plains and Mingyun Village. There are some Hilichurls nearby, so players might have to defeat them first before they can enjoy their fishing time.
Luhua Pool
To access the last Golden Koi spot in Liyue, Travelers can teleport to the domain in Luhua Pool. If a character steps on the Pressure Plate in front of the domain, a wind current will appear. This can be used to escape the hole by gliding instead of climbing.
Seirai Island
The last spot for Golden Koi is available in Inazuma. Just like Mondstadt, Inazuma also has one location for Golden Koi. People can use the Statue of the Seven in Seirai Island to quickly reach the place.
It's important to remember that Golden Koi will only eat the Fake Fly Bait, so players have to craft them before each fishing trip. If they don't have the recipe to craft the Fake Fly Bait, then they have to buy the blueprint from Nantuck first. To make Fake Fly Bait, Genshin Impact players will need Sakura Bloom and Horsetail, which can be found around Inazuma and in Dihua Marsh respectively. This type of bait is also used to catch Pufferfish.
All the angling spots, except for the one in Stormbearer Mountains, also feature the Rusty Koi. So Travelers can fish the two species at once. Both Golden Koi and Rusty Koi are needed to unlock the Catch polearm. Also, like other fish caught in the fishing system, both can be used ornamentally in the Serenitea Pot or processed for fish meat.
Rusty Koi can be caught with Golden Koi in the Wangshu Inn, Mingyun Village, Luhua Pool, and Seirai Island fishing spots. Additionally, it can be caught in the Cider Lake near the Whispering Woods, though Genshin Impact players should be aware that Golden Koi cannot be caught in this spot.
Fishing is a new mechanic introduced in Genshin Impact 2.1. The new addition was welcomed by the fans of the popular game. However, fans should keep in mind that they need to be at least Adventure Rank 28 to be able to enjoy the new feature.
Genshin Impact is now available on Mobile, PC, PS4, and PS5. A Switch version is in development.
