This article was updated on January 28 after revealing the correct way to unlock Isu's secret bow in Assassin's Creed Valhalla.
If you want to do it without using any gimmicks (other than those developed by Ubisoft) then head here.
Assassin's Creed Valhalla players found a super-powerful magic bow hidden in a pile of shiny stones, and they found it in a way that the developers had not planned at all. A secret bow created by the alien space gods of Assassin's Creed, Isu, is located under a pile of stones. There is some secret path that no one has found yet, but there is also a way in which you find a pile of rocks and hit it and then reload your save and then hit some more.
The weapon itself is an extremely powerful bow made by the ancient Isu, which is part of the Assassin's Creed story that only people who really really care about Assassin's Creed know. At least the short version is that they are god-like aliens who once ruled over humanity. So ... this is an alien space bow. This is called the Arch of Nodens, a reference to the ancient Celtic god associated with hunting, healing, and dogs, and equated by the Romans with their god Mars.
The video below from the video maker JorRaptor explains how the exploit works.
