If you’re stepping into the role of Naoe in Assassin’s Creed Shadows and appreciate the blend of stealth and chaos, the Stone Heart Kusarigama should be an essential part of your arsenal. This Legendary weapon distinguishes itself not just by raw damage but by inflicting a poisoning effect through chain finishers, enabling you to weaken and manipulate foes during combat.
This guide outlines the steps necessary to acquire the Stone Heart Kusarigama in AC Shadows.
How to Find the Stone Heart Kusarigama

The Stone Heart Kusarigama is locked away inside a Legendary Chest nestled deep within the Veiled Tumulus cave located in the Wakasa region of Mount Uchinakao. However, merely reaching the chest involves encountering some challenges along the way.
Upon arriving at the cave, you will need to navigate through a narrow entrance and follow the cramped corridor until it expands into a larger chamber. Be prepared for resistance, as a few enemies will likely be patrolling the area; it’s advisable to eliminate them before proceeding.
As you move further, you will encounter a wall that appears to block your path. Don’t retreat just yet! Look for an explosive barrel embedded in the wall. Use a kunai or any ranged weapon to detonate it, clearing your way ahead.

Continuing deeper into the cave, you will come across another obstacle. This time, you’ll need to climb up some ledges and peer through a small opening in the rock wall, where yet another explosive barrel is hiding. Take it out to clear the path, and not long after, you will find the Legendary Chest containing the sought-after Stone Heart Kusarigama.
Unique Features of the Stone Heart Kusarigama
The Stone Heart Kusarigama stands out from other variants due to its focus on Poison Buildup. At Level 60, it showcases impressive stats:
- Weapon DPS: 2078
- Posture / Headshot DPS: 7479
- Ability DPS: 11426
- Poison Buildup: 18.00%
It is important to note that this weapon’s distinctive Engraving only activates the poison effect when executing a Combo Ender. This means players must master the art of chaining attacks consistently to deploy its full potential effectively.
