This guide will let you know where to get Graphorn Horns in Hogwarts Legacy.
You need to progress toward the end of the story, and there will be a mission involving a Graphorn. Follow the story, and you will find the Graphorn Den not too far from the Clagmar Castle.
Once you arrive there, you have to defeat the Graphorn in battle; keep in mind that Avada Kedavra doesn’t work here. After bringing the HP of the beast down to zero, you can catch it as normal using your nap sack.
Now return to your base operations in Hogwarts at the room of requirement, go into any vivarium, and put the beast down. Then you need to feed it and brush it once using the brush and feed spells.
