It’s a “savage power hack” as indicated by the engineers.
Players of Assassin’s Creed: Valhalla have discovered a super-amazing sorcery bow covered up in a heap of sparkling rocks, and they’ve discovered it such that the designers totally didn’t expect. The mystery bow, made by Assassin’s Creed’s outsider space divine beings, the Isu, is situated under a heap of rocks. There’s some mystery way that no one has very found at this point, but on the other hand there’s where you discover the heap of rocks and hit it a few and afterward reload your save and afterward hit it some more. Here’s AC Valhalla Narrative Director Darby McDevitt on the hack:
The weapon itself is a very amazing bow made by the old Isu, which is important for the legend of Assassin’s Creed that solitary individuals who extremely care about Assassin’s Creed think about. The short form, in any event, is that they’re supernatural outsiders that used to govern mankind. So… it’s an outsider space bow. It’s called Nodens’ Arc, a reference to the antiquated Celtic god related with things like chasing, recuperating, and canines, and likened by the Romans with their god Mars.
