Serpentbone Blade is a Katana in Elden Ring. The Serpentbone Blade scales primarily with Strength and Dexterity and is a good Weapon for high Dexterity characters to engage in mid-range combat. It is capable of inflicting both Slash and Pierce attacks.

 

Sinister katana modeled after a serpent bone.

The densely packed row of spines that jut away from the cutting edge are coated in a lethal poison.

Serpentbone Blade Notes & Tips

  • When Poison is procced on an enemy using this weapon, the resulting poison effect will deal double the damage per tick but last a third of the amount of time compared to poison procced by other means. This is referenced as "Lethal Poison" in the weapons description, but "Deadly Poison" in other weapons/items. Overall, Deadly Poison will do less damage than regular poison if both are left for their full duration. (Fetid Pot and Venomous Fang also have the same effect)
    • Its shortened duration can actually serve additional benefit; by reducing the uptime, it allows for more frequent triggers of certain damage boosting gear. The Mushroom Crown and the Kindred of Rot's Exultation can utilise this to great ends.
  • Weapon Skill: Double Slash.
  • This weapon cannot be infused with Ashes of War.
  • Serpentbone Blade can be upgraded by using Smithing Stones.
  • Causes Poison Buildup: poison status effect elden ring wiki guide 100px (66).
  • Can't be enchanted with Magic nor boosted by Consumables.
  • At 80 Dex, this weapon has an AR of 598 (294+304)
    • Compared to a Keen Uchigatana, which has an AR of 596 (258+337), the Serpentbone Blade has negligible higher damage, and deals more status effect (66 poison, vs 45 bleed).  Uchigatana maintains higher reach, but has lower base damage, so it only begins to outperform at higher levels.
  • This weapon has a unique R2 that consists of a double slash.
    • The initial hit of the R2 comes out exceptionally fast, but does limited damage, useful for staggering lower poise enemies who will then be hit by the higher damage second attack.
    • Charging the attack causes your character to take a large step forward before delivering the double strike, making it a useful tool to close distance with dangerous enemies while still dealing considerable damage.
    • Because every weapons R2's normally counts as 2 hits towards "successive hits" talismans, AND this weapons R2 is a multi hit attack, this attack can make a single R2 allow you to gain 1 stack of all those talismans/items that boost the damage with successive attacks. (See examples below). This is because it takes a minimum of 3 hits to activate damage buff type "successive hits" talismans and one slash of the R2 counts as 2 hits while the one afterwards will count as a third hit. Whether the first or second slash counts as 2 hits is not known as of now.
    • The best setup to take advantage of the multi hit R2 is: Millicent's Prosthesis + Rotten Winged Sword Insignia (or the regular version if you don't plan to go into ng+ or having it dropped by another player) + Kindred of Rot's Exultation (if you can proc poison)+ Shard of Alexander (since the Skill is also a multi hit) and then Thorny Cracked Tear for your Flask of Wondrous Physick. 
  • Sell Value:  er runes 13 200
  • Despite being locked to the Standard Affinity, it cannot be enhanced with Magic nor Consumables. It receives no Arcane scaling, yet has inherit Poison Buildup, and this amount cannot increase per upgrade level. The Ash of War cannot be changed. 
  • Patch 1.07 decreases the poise buildup for dual-wielded weapons, however, the poise damage when you two-handing Serpentbone Blade increased. Which affects the fighting style of builds like Serpent Samurai.
  • NOTE: As of Patch 1.08Katanas poise damage has been reduced only on PVP.
  • NOTE: As of Patch 1.09, the scaling values of this weapon were changed. Please refer to the Upgrades Table of this weapon below.

      Now that I’m doing an arcane run I can truly appreciate how disappointing this weapon is for having no poison scaling

      • > Upgraded with regular Smithing Stones
        > B scaling in Dexterity
        > Has generic version of Double Slash as a skill
        > Can't replace the the skill with an Ash of War
        > Why?

          Most confusing weapon for me, I just can’t understand why it’s done this way, why? And still I fell in love with it

          • Anonymous

            AoW should have been unique considering its locked. Serpent's bite and be a poison version of piercing fang or a unique double slash since the charged heavy is a double slash. Even a special version of poison moth flight would have been better

            • Anonymous

              I love this weapon. Great for proccing all those successive attack talismans and while it doesn´t seem to be a weapon for sword and board at first glance, you have to try guard counters with it, they are lightning fast. It´s incredible.

                Casual 1500+ AR on a katana with buffs from a bunch of equipment active, and you get a cool mushroom man drip as a bonus

                • Anonymous

                  In Elden Ring 2 I hope there's a new rule to ashes of war: If you lock the weapon's ash, It must not be a generic ash, IF it is, it MUST be a enhanced version.
                  More hits, more damage, more reach, anything, make it visually distinct too.

                    This thing is great when using it to not have the enemy lose any poison buildup. The double slash is not as bad as people say, because two imputs almost guarantee a proc.

                    • Anonymous

                      This sword could have been so much better with Poison Moth's flight as the ash of war. :/ The special R2 makes Double Slash so redundant...

                      • Anonymous

                        The fact that such a cool heavy attack went to such an ugly weapon makes me unreasonably angry. If anyone ever makes a mod that gives this weapon's R2 to something like the Dragonscale Blade, hit me up.

                          I didn’t believe in this weapon, but after using it with rot exultation, consecutive attack buffs and mushroom hat… yeah, I’m a certified serpent boner now

                            Interesting Detail is that this sword seems to have been made for a left handed wielder. If you look at the weird coiled snake hand guard it would be more comfortable to wield in a left handed grip

                              i like it, it makes pvp players more aggressive, since they are poisoned and often forget about their Neutralizing Boluses

                                Lol you can tell who’s bad at the game when they say they want a poison version of corpse piler on this like just say ur not good at the game

                                  I’m one of the people in the comments shitting on the weapon ( the one that says they’re forcing themselves to like it), but it’s honestly my favorite weapon in the game now. It’s ok that it doesn’t have arcane scaling, cause the AOW and unique R2 specialize in quick strikes that more than compensate for lack of arcane scaling.

                                  The deadly poison effect does good DoT damage in a less amount of time, so I always want to stay in the fight so I can be able to proc the poison again.

                                  Plus with the successive strike, and attack buff from poison talismans, I feel more involved in the fight overall with this weapon. It’s definitely not the best or flashiest weapon in the game, but it’s been the most fun for me as a pure Dex build character

                                    - Gorgeous visual design
                                    - Solid status buildup
                                    - Unique, powerful R2
                                    - Double Slash is a good AoW
                                    - Solid scaling
                                    - On the lighter side of Katanas (by like half a Miyazaki)

                                    Cons
                                    - No bleed buildup (all but 2 Katanas have bleed)
                                    - Poison is kinda underwhelming
                                    - Can't change the AoW
                                    - Mediocre length for a Katana
                                    - Not buffable with magic or greases
                                    - USES REGULAR SMITHING STONES???

                                      this weapon is extremely confusing in it's design. It's upgraded with regular stones yet can't be infused, change ashes or war, or buffed with magic of consumables. Everything says it should use Somber stones yet it doesn't have a unique ash of war like most somber weapons. This issue occurs more then I'd like for a lot of weapons. What's the point of ashes of war if I can't even use them on the coolest weapons.

                                        My only question is why this one dosnt have Poison Moth Flight as a unique weapon art?
                                        This would be so much cooler than double slash.

                                          This weapon could've been so cool. Reminded me of Ds2 Manslayer, the only game that actually had viable poison damage.

                                          Put double slash poison infusion on an uchigatana and you'll get higher poison dmg AND bleed then this disappointment. Only thing really cool about it is it's double slash R2s, but otherwise it fails it's own genre.

                                            it would be cool if this double slash had a rivers of blood type thing where it shoots out poison (or if this weapon had poision moth flight or som s***)

                                                Fine if you're just really wanting to run a poison build I guess... but poison is objectively worse than bleed in every way so I mean why even bother? And even then you'd get better results putting Poison Moth Flight on an Uchi because it's just a better weapon skill for proccing poison and then it can scale with arcane.

                                                    Soooo you can put ashes of war on the rot rapier, but this is stuck with a generic ash of war, is unbuffable, and a pain to upgrade on the first playthrough. The only thing this outperforms other katanas on, or even other weapons, is the style points. I loved this weapon when i first got it, but its only such a dissapointment on all fronts.

But Clayman's Harpoon is okay, cause we don't follow our own rules. At least we can change Yura's unique Piercing Fang, and not basic Double Slash amiright. Stuff like this, Gargoyle Blackblade weapons, etc should be more viable & adaptable...

Also double slash is an interesting choice for aow since it’s R2 is so similar to double slash. It’s still hella fun to use and pretty effective with the right build.

                                                                    • Anonymous

                                                                      • Anonymous

Its a recusant reward to be used against other players. The unique R2 and the (unfortunately) locked AOW are there to give you more hits and more poison buildup. This thing's poison is almost as strong per tick as SR, it just doesnt last as long doing less total damage. I use it as a twink weapon because low level hosts tend not to have boluses. With solid damage and ghost hits causing poison this can be an absolutely brutal chasedown tool as well as a solid general weapon. In PvE I use this to apply its poison and switch back to whatever.

                                                                        • Anonymous

                                                                          • Anonymous

It sucks you can't at least infuse this weapon, because I don't see why it should be locked to the most basic AoW.

                                                                            • Anonymous

I don't know why they are so happy with making so many weapons worthless. They do this in all their games since Armored Core. Weapons can look cool, or feel cool but often be trash. Other weapons will be clunky, and boring, but be broken in the meta. They've no real desire to just make a game full of interesting, valuable and useful tools. It's very bizarre.

                                                                              • Anonymous

You’ve got rivers of blood with the same skill but extra range as well as arc scaling and this which has the basic skill and no way to increase poison buildup. I’d rather just have the skill changed to poison moth flight to make it more unique and either give it a bit of arc scaling or increase the buildup slightly

Think about how cool this weapon would have been if you could put poison moth flight on it, or at the very least came default with it instead of double slash. It's much more fitting imo.

It’s obviously not the best katana but it’s certainly not a bad one. Some of y’all can pointlessly compare it to the best katanas in game or say it isn’t viably for a status effect build(like no **** dude it’s obviously a dex weapon lol, ofc there’s better alternatives for that kind of build) but that doesn’t mean it’s generally bad lol. It would be nice if we can put different affinities and ashes on it. But I think it’s pretty balanced for what it is. The moveset, ash, and deadly poison compliment each other very well. It get proccs off fairly quickly even when you’re not focusing on trying to apply the status effect. It’s a B tier weapon imo and some of y’all need to understand that not everything in the game has to be so versatile, instant proc, or op.

                                                                                                  • I'd like to believe this sword's effect is the game's official take on Toxic from the older games. Scarlet Rot is technically the successor, but in the message options, 'toxic' is still under the affinities section. While DS3 never had a weapon for Toxic affinity (there was a staff that had a Weapon Art that dealt unique poison damage, I think?) both DS1 (Gravelord Sword) and DS2 (Bent Blade) did. If I'm reading into it right, this is also a separate status that likely shares build-up (bar/icon) with Poison, which is what DS3 inevitably did.

                                                                                                    Just my two cents.

Double slash is pretty good and kinda works great for the weapon's low build up with multi hits. You don't need Poison Moth Flight as the poison duration is actually short for the rot talisman. Because of the lunge it's also a good mixup with the R2. A single R2 triggers the multi hit attack boost talismans/physic which is too good with how quick the R2 is. High build up might be mandatory with bleed and frostbite but I think it's fine to be low on poison(and rot). You can't really reapply it quickly and the damage gain from infusing with keen/heavy vs poison would most likely equate to a higher DPS than waiting for the poison ticks unless you play super passively. My only complaint is why this isn't a somber weapon.

                                                                                                      • Anonymous

Its double slash DOES apply a hefty amount of poison, it feels as effective as Corpse Piler does. However, I'm pretty sure that RoB's weapon art Corpse Piler does have added range with the bloody arc coming off of it, which is something this sword lacks. I think if it at least had that (another commenter mentioned wanting green goo to fly out of it) it'd be perfect.

Doesn’t need a buff or tuning in the scaling department. It’s R2s are fantastic for mixing up with double slash and roll catching. It may actually need a slight nerf. But with the range being so short… maybe not.
