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.
  • The sword must be charged fully to unleash a powerful wind attack.
  • Highly effective against Yhorm the Giant.
  • Contrary to its description, neither its skill or regular attacks do extra damage to regular giants. 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.
  • 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.

      So does storm ruler's weapon art actually damage anything else other than yhorm? I've tried it during PvP, PvE, and it'd be total crappola if FromSoft just made this one weapon hurt one specific boss.

      • 21 Feb 2017 20:40  

        imo yhorms a way better fight when killing him with your standard gear than just cheesing him with storm ruler. fromsoft even made it so that you can get visceral attacks on his head if you do enough damage to it through ways other than the storm ruler! yhorms way more satisfying without the storm ruler imo. i highly recommend trying it out yourself.

        • 29 Jan 2017 10:49  

          Weapon art dmg scales with each following ng+ but only to yhorm the biotch. It will always 5-shot him unless you coop. Was doing 12k in ng+7 with each hit, Jesus TF Christ!

          • secret tracking26 Sep 2016 14:47  

            the fully charged weapon has a secret tracking that does that if your enemy dodge to the side and i out of your visual tracking then if you're locked on you will see the wind blade hit another place but the dust that blows to the side is aiming at your enemy and you'll still hit them

            • Yhorm gave the second Storm ruler to Seigward19 Sep 2016 16:17  

              It all makes sense now. <br/><br/>His " Sworn Duty " was to ... Kill Yhorm when he became a Lord . <br/><br/>ouch.

              • Curse Rotted Great Wood17 Jul 2016 01:44  

                I fought Yhorm with Siegward and got both storm rulers and saw messages telling me to use it on the curse rotted great wood, went to new game plus, but for some reason it does'nt work on it! Is there a reason or do I just need the new sotrm ruler?

                • Siegward!06 Jul 2016 06:41  

                  Made it happen Siegward appeared in the Yhorm boss battle. I ran to the corpse and picked up the Stormruler. As I turned around, Siegward was already dead and won't respawn although he is undead as the player is. For me some parts of this game aren't logical...

                    this is a stupid rematk as it it is obiously just a regular twohander missing its grip

                    • Swagruler17 Jun 2016 04:37  

                      Yhorm be like "yo I got tons of health and you ain't gonna do ***** to me with that puny ass sword" *pulls out stormruler* "Oh ***** ***** me"

                      • Copies.13 Jun 2016 13:44  

                        Fromsoft needs to erase restrictions applied to this particular weapon. Having 5+ copies is not a big deal by any means, but not being able to discard it at all is a little annoying. Like, it is SO sturdy that no heavenly strength can bend it? And yet it has 10 durability and breaks after 10 hits. No logic here. None.

                        • Tell me10 Jun 2016 23:00  

                          why was this weapon brought to DKS3 in the first place? So basically they just brought this weapon over from demon souls and said that this was something that Yhorm created?

                          • Honorable Yhorm09 Jun 2016 05:49  

                            It was rather honorable of Yhorm to create his own Achlies' Heel. Shame the purpose of why this sword was created came true. I would like to know what Yhorm was like in personality...FROM SOFTWARE. MAKE A DLC WHERE YOU CAN TALK TO EACH OF THE LORDS IN THE TIME PERIOD BEFORE THEY BECAME LORDS.

                            • Storm Ruler "Storm King" Skill06 Jun 2016 12:56  

                              Does the skill scale with strength or dexterity?<br/><br/>Does the skill's damage increase with weapon upgrades? (+1, +2, etc.)

                              • Hilarious03 Jun 2016 07:00  

                                So much fun, i killed yhorm at lvl 25 with siegward giving me two Storm Rulers! After that i headed down to the High Wall of Lothric and did some low level pvp. Since nobody really has very damaging weapons your not at a massive disadvantage making it a kinda even match up. Probably one of the funnest things ive done in dks3 as its a challenge to even get the Storm Ruler in the first place, and ontop of that it requires adept mechanic ability to win with this literally stick with a sharp point.

                                • Storm Ruler22 May 2016 08:34  

                                  If the Storm Ruler is highly effective against Yhorm, why can't I get it BEFORE I have to fight him? I'm currently stuck at the Yhorm fight because I don't seem to damage him enough to get half his health after half an hour of hitting him!
