The Storm Ruler is a greatsword in Dark Souls III.

In-Game Description

Greatsword with a broken blade, also known as the Giantslayer for the residual strength of storm that brings giants to their knees.
Yhorm the Giant once held two of these, but gave one to the humans who doubted him, and left the other to a dear friend before facing his fate as a Lord of Cinder.
Skill: Storm King
Assume stance to imbue sword with storm. Most effective when facing giants.



To activate the Storm Ruler's skill, Storm King, the player first needs to wield the weapon with both hands and press and hold the Left Strong Attack button (PlayStation - L2 - 01 / Xbox 360 - Trigger Left - 01) for five seconds to charge the blade (the blade's charge will not wear out in time).

While still wielding the sword with both hands, press and hold the Left Strong Attack button (PlayStation - L2 - 01 / Xbox 360 - Trigger Left - 01) once more to acquire an offensive stance and then press either the Right Weak Attack button (PlayStation - R1 - 01 / Xbox 360 - Bumper Right - 01) or the Right Strong Attack button (PlayStation - R2 - 01 / Xbox 360 - Trigger Right - 01) to unleash a two-handed slam attack on the ground which will call in a powerful storm, sending it forward.

  • The Storm Ruler's skill, Storm King, imbues the blade with the power of storm, allowing it to deal heavy damage to giants.
    • This ability can almost be considered a requirement while facing Yhorm the Giant, since most other attacks will deal very low damage to him.
    • Hitting Yhorm's upper body with other weapons will still deal heavy damage to him - the bonus damage is not tied to the Weapon Art itself, but rather to Yhorm's upper body. High-reaching attacks, such as those from Ultra Greatswords, can hit for high damage if the attack connects with Yhorm's head or upper body.
    • Contrary to the description, the skill only deals high damage to Yhorm. Other giants will take the same amount of damage as any other enemy, and are not staggered by it.
  • The Storm Ruler cannot be sold or dropped.



Reinforced with Titanite Scale.
