If you’re aiming to grab the fancy Polearm called The Catch, you’ll need to start scouring Genshin Impact Rusty Koi locations. This rarer fish is found in certain spots across the entirety of Teyvat, and you’ll need to catch plenty if you want to earn The Catch quickly. Below, we’ll explain where to find Rusty Koi locations in Genshin Impact so you can fill your baskets with tasty fish for crafting and cooking.
Genshin Impact Rusty Koi locations
You’ll find Rusty Koi locations spread very sparsely across the nations of Teyvat. So far we know of five locations total. In Mondstadt, you’ll be able to catch Rusty Koi at the lake edge directly east of Mondstadt city itself, as marked above.
Over in Liyue, you’ll find two Genshin Impact Rusty Koi locations close to Wangshu Inn. One is across the deep waters to the northwest, southwest of Dihua Marsh. The next is found in the broken bridge segment southeast of Wangshu Inn, on the route to Mingyun village. For the last, you’ll need to head further south to fish in the water at the beach north of the domain in Luhua Pool.
Finally, Inazuma holds one Genshin Impact Rusty Koi location on the new Seirai Island. Here you’ll want to fish between the northern two island segments, east of Koseki Village and west of Fort Hiraumi, as shown above.
Those are all the Genshin Impact Rusty Koi locations that we know of so far, but we’ll attempt to update this guide if we discover any more.
