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, but can be Buffed with Weapon Art (WA)
  • Maintaining the LT/L2 WA stance long enough will engulf the sword in a storm, buffing it. 
  • The weapon will remain buffed until the storm is projected as described below. Consequently, a player can buff their weapon and do normal light/heavy attacks with the storm imbued blade.
  • Before the blade has been imbued with the storm, while the sword is held in the stance, pressing either r1 or r2 will execute the normal stance weapon arts(lunge and the guardbreak spin respectively), and doing so will consume fp (the storm projectile does not). This is quite unkown, and such usually catches players off guard.
  • To fire the storm as a projectile, assume the WA stance and press RT/R2 immediately if the weapon is already buffed. If not, the player will have to remain in the WA stance until the buff takes effect.  
  • 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 WA nor regular attacks do extra damage to regular giants, with the exception of Yhorm himself..
  • 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.

      "Appears the design is inspired by the "Kusanagi" sword, one of the Three Imperial Regalia of Japan."
      In my opinion it looks exactly like a zweihander with the hilt broken off. The place where the Ashen One holds it appears to have been part of the blade that appears to have been ground down enough to comfortably hold under leather wraps. Which I think is something that could have been done to give this old sword some extra miles.

        Such a waste of a weapon. Was so excited when I got it, only to try it on other giants and realise it only works on Yhorm. When even is the point of description calling it Giantslayer when it barely tickles the common giants even with WA, smh

          "Appears the design is inspired by the "Kusanagi" sword, one of the Three Imperial Regalia of Japan."
          In what way? I looked (Wiki) it up it's a mythical unseen sword.

            Why did Fromsoft reused something from fcking DeS in Dark Souls 3 man, this is just unnescessary fanservice and doesen't make any sense story-wise. Downvote me as you like, it still think it is stupid

              Couldn’t get this to work consistently on Yhorm. Sieg died while trying to figure out how to use it. Apparently, his wasn’t working consistently either. He doesn’t revive on respawn. Be careful.

                It is a very good option when you invest very little in STR or DEX but count with plenty of poise. As a pyromancer with a lot of armor but only INT and FTH, this is welcomed with a smile.

                  I got the one near the throne for fighting Yhorm, but weeks after killing him wandered back through and found a second one on the ground, at the opposite end of the room. Is this normal?

                    A good chunk of this info is incorrect:
                    1. The WA buff does not “buff” the weapon, no additional damage is added

                    2. The Charged Sword Weapon Art DOES consume FP and all of your stamina too. Normal WA’s uncharged also consume FP

                      Timed correctly in the boss fight against Yhorm, if you have Siegward of Catarina by your side, it is possible to stunlock big daddy Yhorm.

                      Or, at least, it felt like he was stunlocked because he didn't really do much.

                        To make the most of this weapon, when you're charging up the WA, find a new weapon, find 3 titanite shard, 3 large titanite shards, 3 titanite chunks, a titanite slab, and a gem of your choosing. Then, grind souls to maximize the damage of your new weapon. Then, find a part time job. Work your hardest and build up money. Then, when you have enough to sustain yourself for a while, go to community college. Now, with your new diploma, find an ok job. Build up money over time. Now, go to university, I would reccomend something in a STEM field. Stay in school and work your hardest again to get a bacjelors degree. After you've used this to find a good stable job, I would reccomend following your passions and finding love. Once you are sure someone is the one for you, propose to your soon to be spouse. If all goes well, they should say yes. Now, build up a family, and build up enough money to start a family. Keep supporting your children by working until they are a few years past college graduation- just in case they have issues come up. Now, use your savings to retire. Live in comfort and ease. Now, when you're old and on your deathbed, surrounded by loved ones, the weapon art should be charged up. Press r1 and show your family that cool whirlwind thingy.

                          Anybody down to make Storm Knights in your games guys?
                          Made one with all the storm weapons recently and I'm having a blast with it.
                          - Sellsword Helmet
                          - Dragonscale Armor
                          - UndeadLegion Gauntlets
                          - Fallen Knight Leggings

                          Lemme know if there's any other fashion that would work well I'm trying to do all sorts of them.
                          Also if you can give me tippers on what set of rings you used on it that would be super cool.

                            Why is there a message by Yhorm's throne that says something like "Only a storm can fell a Greatwood"? Does Storm Ruler deal extra damage to the Curse-Rotted Greatwood?
