Storm Ruler is a Weapon in Dark Souls 3

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 that 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.

Notes and Tips:

  • Cannot be Infused or Buffed.
  • Reinforced with Titanite Scale.
  • At 40/40 it has 485 AR.
  • Has 10 durability and is very easy to break. Recommended to use Wood Grain Ring to increase its durability.
  • It doesn't have any stat requirement to be used, meaning that a mage without any strength and dexterity investment can still use it.
  • Contrary to its description, neither its skill or regular attacks do extra damage to regular giants.
  • Cannot be sold or discarded, extra copies can be stored in the bonfire stash. 
  • The Storm Ruler is a callback to the weapon of the same name in Demon's Souls.
  • Appears the design is inspired by the "Kusanagi" sword, one of the Three Imperial Regalia of Japan.

        Something I found interesting, the design of Storm Ruler in DS3 looks a lot like artist impressions/interpretations of Kusanagi-no-Tsurugi ("Grass-Cutting Sword"). The original name for the blade however was Ame-no-Murakumo-no-Tsurugi ("Heavenly Sword of Gathering Clouds"). Don't know if it's connected at all but I thought it was a neat observation.

          I do hope in the future releases(if any for Dark Souls specifically) that if they bring back weapons like this one, that it'll have more effective uses than just against Yhorm primarily. It's such a fun weapon, even with low durability it still has a nice ranged skill. Even though it's more weaker on normal enemies, good for aggro on enemies.

            I was hoping that the Storm Ruler would be effective against "King of Storms", as it was effective against "Storm King" in Demon's Souls. Would've been a lot cooler to make Yhorm a real fight and then have the optional boss' first phase be the cinematic fight that leads into the incredibly challenging Nameless King fight. And it makes sense, given how the King of Storms fight actually functions. Flying up and hitting you with ranged attacks, as well as it'd be a lot easier to hit it than to go for close range melee hits in an arena that messes with my depth perception ever so much. (I also find his head to move rather awkward for melee hits, but maybe I just suck.)

              does upgrading it to +5, and having 99 str and 99 dex allow to one shot yhorm, or does the damage not increese

                Pretty annoying how you end up stuck with one or two undroppable/unsellable versions of this sword because someone at FromSoft forgot to remove the "key item" tag from them after the Yhorm fight.

                  " This is most likely due to the fact that Yhorm resembles the giants from Dark Souls 2, which are different from the aforementioned giants that come from Dark Souls 1. " No he he has a face. DS2 giants don't have faces.

                    In pvp, the closer your opponent more DMG this weapon skill will do. So, if your opponent is using light armor it does up to 1k dmg very close and around 550 dmg to full havel armor. at medium distance it does around 500 dmg to light armor and 200~300 to heavy armor. this WA has insane poise but paifully slow, so its recommended to use WA against heavy weapon users. go try it yourself, its very fun weapon.

                      How can this thing kill a giant lord without being upgraded, but it needs to be +3 before it can kill a f****ng rat?

                        I got two Storm Rulers in a single NG.
                        I walked into Yhorm's boss fight and Siegward immediately appeared with one of these in hand. I assumed Siegward was the one supposed to kill the boss so I just rolled around and watched onion bro kill the giant by himself. After the fight I was automatically teleported to another boss.
                        When I came back to Yhorm's room I looted the Storm Ruler in front of the throne and then I got a second one along with Siegward's loot.

                          I made an Odinson(Thor) fashion with a STR+FTH build, and use this and a lightning-infused Blacksmith Hammer. Artificially makes the game a bit harder if you're finding it too easy, lol.

                            If I fully upgrade it, does its WA deal more dmg to Yhorm in his fight, or is it just a waste of materials?
