With every new Genshin Impact update, we get new characters in the game, and to ascend them, we need to farm their ascension materials. One of them is the Fontemer Unihorn which is an ascension material required to ascend characters like Neuvillette, and it will become available in Genshin Impact 4.1 update to farm.
As per its in-game description, it is "The electricity-emitting section of the Millennial Pearl Seahorse, and its regalia, the symbol of its surpassing might — now snapped off amidst a clash against a mighty challenger." Since Fontaine will be expanding with the new update, you will be able to find Fontemer Unihorn in the new areas; however, it will be a difficult task to explore a massive region to farm them, and thus, here are their exact locations to save you a lot of time.
Genshin Impact: Fontemer Unihorn Farming Location
As per the in-game description, Fontemer Unihorn is a drop that you will get by beating Millennial Pearl Seahorse, the new boss coming to Genshin Impact 4.1 update. You can have a look at its location marked on the map below:
You will need a total of 46 Fontemer Unihorn to ascend Neuvillette to his highest level, and based on the clip shared during the special program livestream, in order to beat the boss, we would recommend you to create a party including Pyro ranged DPS like Yoimiya along with Cryo character like Ganyu.
In addition to this, we would recommend you to have a shield character like Zhongli to save yourself from the incoming damage. Lastly, you can have a healer like Baizhu who will help your team heal, and Dendro's elemental reactions will help you deal extra damage to the Millennial Pearl Seahorse.
You can activate the nearest Teleport Waypoint to the boss to travel to its location quickly. In addition to this, make sure that all of the characters in your team have full HP before starting the fight with the boss.
