Now, when the trigger is pulled, the sword fires a beam, much like when Maliketh uses it against you.

In Maliketh's Black Blade Elden Ring (U11.2) Black Blade mod scales primarily with Strength, Dexterity, and Faith. It is a good Weapon for inflicting holy-based damage. The sword from in-game is inspired by the Fextralife Wiki: Maliketh's Black Blade is a Colossal Sword in Elden Ring.

Maliketh's black blade which once harbored the power of the Rune of Death. A sad shadow of its former glory. After a fragment of Death was stolen on that fateful night, Maliketh bound the blade within his own flesh, such that none might ever rob Death again.
