Assassin’s Creed Valhalla players figure out how to get secret Isu bow properly While Assassin’s Creed Valhalla came out late last year, players are still wandering around looking for secrets. Earlier this week, players discovered that you could fetch a secret, powerful Isu bow from a pile of rocks by smacking it with your sword, saving, and then reloading the game. That’s not how you’re supposed to do it, obviously, with narrative director Darby McDevitt calling it a “clever, brute-force hack”. Now, though, players have stumbled across the proper way to get the Noden’s Arc bow. Assassin’s Creed content creator Access the Animus followed a series of clues in the Viking game’s Collector’s Edition to discover that the rock could only be broken by someone using Excalibur at sunset.
