In the expansive world of Genshin Impact, players will frequently encounter weasels. However, native to the Natlan region, a unique variant known as the Furnace Shell Mountain Weasel has emerged due to extensive exposure to Phlogiston. This extraordinary creature showcases distinctive traits that set it apart from its common counterparts.
Utilizing a Secret Source Core, Furnace Shell Mountain Weasels possess the ability to burrow underground and launch surprise attacks on players. To thwart these creatures effectively, it is recommended to target the Core directly. Although attacking the Core can earn a swift victory, the quickest method to lure them into the open involves executing Plunging attacks. Once the Core is rendered inoperative, the weasel will remain temporarily paralyzed, providing an invaluable opportunity to collect desired item drops. For players seeking guidance on where to find these foes, this article will outline the locations of Furnace Shell Mountain Weasels in Genshin Impact.
Furnace Shell Mountain Weasel Locations in Atocpan

Within the Atocpan area, players can discover five distinct Furnace Shell Mountain Weasel locations. Here’s how to locate each:
- Begin by teleporting to the waypoint situated south of the Ancient Sacred Mountain entrance (close to Derelict Masonry Dock). Proceed west to find a Furnace Shell Mountain Weasel near a Fatui camp.
- Teleport north from Remnants of Tetenanco, then venture northeast into an opening where another weasel waits.
- Exit the cave region and head southeast to track down the third Furnace Shell Mountain Weasel.
- Utilize the Teleport Waypoint located east of the Ancient Sacred Mountain entrance, then navigate north to discover a ground fissure. Engage the Phlogiston spouts to summon the Furnace Shell Mountain Weasel—this process mirrors the mechanics used to heat hot springs during the “Is ‘Intensity’ Really The Key?”quest.
- Your journey concludes by teleporting to the northwestern waypoint in Atocpan, then walking southeast to encounter the fifth weasel.
Furnace Shell Mountain Weasel Locations in Ancient Sacred Mountain

There are also five Furnace Shell Mountain Weasel locations in the Ancient Sacred Mountain area. One notable location hosts two weasels, making it a prime spot for players. To find all these locations, follow the steps below:

- Proceed to the only waypoint located on the eastern island in Ancient Sacred Mountain and continue moving north.
- Transition to the Dragon’s Residence layer of the Ancient Sacred Mountain. Utilize the northernmost waypoint in the Ruined Armament Workshop and travel south.
- The fourth Furnace Shell Mountain Weasel can be found in the Heart of Force Inversion area.
- Finally, locate the last weasel south of the Pseudostar Pedestal. This specific weasel is part of a twin pair, offering the opportunity to achieve the “Two Weasels in a Trenchcoat… or Was It Three?”achievement.
With these detailed locations, players can effectively hunt and collect from the elusive Furnace Shell Mountain Weasels scattered throughout Genshin Impact.
