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. 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.

      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?

                    In pvpi did more than 1k dmg on light armor and around 600 to heavy armor with WA. THIS WEAPON IS NOT USELESS

                      Whoever thought at From that it would be a good idea to make the Stormruler permanently stick in one's inventory with no way to leave, discard, or sell it, should be shot in the f-ing kneecap. "HURR DURR DARK SOULS DOESN'T HOLD THE PLAYER'S HAND!" my ass, if someone is stupid enough to sell it or otherwise get rid of it before they kill Yhorm or indeed, read the item's description and make the deductions from it, they DESERVE IT. On the other hand, covenant rewards that can't be replaced by any means CAN be sold, left, or discarded. Way to go. Not like killing Yhorm without the SR is impossible to begint with. Worst case scenario, summon phantoms. I have 5 of the damn things and it triggers my OCD hard, even though I put them in storage box. Also, as a weapon, this thing is bloody useless, once again, why, From? Why do you make a weapon that is good for a single fight but completely worthless otherwise? What the f were you thinking?

                        I feel like Stormruler should have been an ultra greatsword, considering "Yhorm once held two of these." In his hands, they'd probably look like and be about as effective as toothpicks. It's not a soul-transposed weapon, either, so you can't even make the comparison that Yhorm's Great Machete becomes 1/10th as big on the player's character.

                        And, idk, it would also be kind of cool if they made it somewhat more viable outside his boss fight.

                          Am I missing something? Obviously this sword is amazing against Yhorm and its WA is really cool, but my experience otherwise was that it was pretty ineffective compared to other swords in normal combat.

                          Related to the visually cool swords comment, I had the same thought with the Onyx blade from AoA. That thing looks amazing and with a dark build it's quite viable for general use.

                            One of the coolest weapon in the game. One thing I didn't like in DS3 is the fact that the awesome visual weapons are generally speaking crappy while the simplest weapons are the best like: Broadsword, Straight Sword, Astora Greatsword, Hand axe.

                              I've been thinking. So this sword is used to kill giants, which proves Yhorm is a giant. But he is also a lord of cinder, meaning he is a human/descendant of the pygmies who found the dark soul, because according to the Ringed City DLC, the humanity's existence was tied to the 1st flame, dooming them to link the fire forever. Then there's Gwyn, who is a god of the old age and clearly not human, but also the first lord of cinder. So a god can link the 1st flame too, which also explains why the Soul of Cinder's 2nd phase emulates Gwyn's spirit. So does that mean any being, regardless of race, can link the 1st flame, so long as they have a huge amount of souls? And does that mean of all the races, only humanity is forced to link the flame because of the curse and their connection to the abyss/dark soul? Also, is it possible that the DS2 giants are simply hollowed versions of Yhorm's race? And does the fact that Yhorm is both a giant and a lord of cinder mean that giants are just BIG people, like how there are huge humans in One Piece? Lastly calling Gwyn and his children godly, is that explicitly addressed to their race, or are they called gods because they have a kickass souls? Because aside from some obvious differences, they look pretty much human...
