The Black Knife is a Dagger in Elden Ring. 161 physical plus 159 holy at max standard with C Faith, and the ranged Blade of Death skill.

When to Use It

---

Mid game. It is found around Altus Plateau, which opens up past Stormveil Castle, so it arrives once a build has taken shape.

Why Players Pick It

---

• 18 Faith required; drops from the Black Knife Assassin at Sainted Hero's Grave.

Upgrades

---

• Upgrades with Somber Smithing Stones to +10, one stone per level.
• Keeps its own skill permanently.

Skill

---

Blade of Death costs 25 FP.

• Unleash the power of the Rune of Death to fire off a blade-like projectile. In addition to dealing immediate damage, the blade reduces the enemy's maximum HP and continues to wear down HP for a while.
• Unique to this weapon. It cannot be moved onto another weapon, and no Ash of War can replace it.

Build

---

It scales Str E, Dex D, Fai D, so Dex and Fai are where the levels go.

• Requires Str 8, Dex 12, Fai 18.
• Takes no Ash of War and no affinity, so the build has to come to the weapon rather than the other way round.

Critical Damage

---

Critical 110. A backstab, or a riposte after a guard break, is multiplied by this, where 100 is the baseline most weapons carry.

• 2 weapons of its class reach higher, topping out at 140.
• It pays for getting behind an enemy or breaking their stance rather than trading hits in the open.

Notes

---

• Dagger once belonging to one of the assassins who murdered Godwyn the Golden on the Night of the Black Knives.
• A ritual performed on the oddly misshapen blade imbued it with the power of the stolen Rune of Death.

Where to Find

---

• Received upon defeating the Black Knife Assassin in front of Sainted Hero's Grave located in Altus Plateau.
