In Assassin’s Creed Shadows, equipping the Heartspiller Bow is essential for players aiming to optimize Yasuke’s potential beyond a mere tank. This remarkable weapon boasts impressive stats and includes a unique passive ability: every charged shot becomes a posture-breaking attack. This feature is particularly advantageous for targeting and dismantling enemy defenses from a distance, making it an excellent choice for a Yasuke bow build.
To acquire the Heartspiller Bow, you must first discover a legendary chest concealed within the confines of the Azuchi Hyotanyama Kofun, a hidden tomb located in the Omi region. Follow these steps to unveil its secrets.
Finding the Heartspiller Bow in Assassin’s Creed Shadows

Reaching the Azuchi Hyotanyama Kofun
Begin your quest by fast traveling to the Azuchi Kukarega point. From this location, proceed directly east, tracing the edge of the map until you discover a hidden structure that serves as the entrance to the Kofun. The specific site is the Azuchi Hyotanyama Kofun, situated just east of Azuchi, at the boundary of the playable area.
Once you arrive, switch to Yasuke — his strength is necessary to clear the blocked entrance to the tomb.
Navigating the Interior

Inside the Kofun, you will find a dimly lit, candle-filled environment. To effectively explore this underground area, be sure to light a few candles. Expect to encounter some resistance from scattered bandits; however, if you’ve appropriately leveled Yasuke, you should be well-equipped to handle them. Clear the area and delve deeper into the tomb.
As you progress, you will ultimately locate the legendary chest. Upon opening it, you will receive the Heartspiller Bow, a remarkable ranged weapon that transforms the mechanics of charged attacks: instead of standard arrows, every charged shot will convert into a posture shot, allowing you to apply immediate pressure on enemies, effectively breaking their guard.
