Onyx Blade is a Weapon in Dark Souls 3. It is part of the Ashes of Ariandel DLC.

      CTRL + F: Claymore. You're welcome. Seriously, this weapon outclasses the claymore/bastard sword as a fashion item mosty. the extra range isn't absolutely to die for. The WA does count as an attack, with minimal range but good stagger. It is absolutely beautiful for a dark pyromancer build (Black flame, serpent, fire orb). Sadly, the game is too old to have Miyazaki make the buff dark damage instead of fire. TL;DR - the fashionable choice for low stat greatsword.

        I really don't understand why a weapon buff literally called blackflame is fire damage instead of dark like the spell it shares it's name with. The fact that the weapon itself has innate dark damage makes me think that this weapon was developed by more than one person and they didn't communicate with each other.

          Using this for PVP and PVE on a 40/40 int/faith pyro build. No problems whatsoever with damage, especially considering as a pyro your main source of damage is spells. The length catches rolls quite easily. And yes if you time the buff right you can get people with it, which they NEVER expect.

            Dark claymore may be more efficent, but this thing has alot more range and it looks sexy. I'm kinda stuck on which one to use lol.

              Sadly, Dark Claymore for pure Dark/Pyro Build [ 40/40 Int/Fai ] will surpass Onyx Blade in damage output even after buffing this weapon with the WA. The AR number will be higher in Onyx Blade, but you will always get less damage.

                It doesn't make any sense that the weapon art adds fire damage. That definitely looks like it should add dark damage. Also... Because it's fire, and the weapon already has split damage, it ends up with triple split damage. yeah... that's not gonna do all that much. It looks hella cool though, fashion souls pyro greatsword.

                  Why do people keep forcing those terrible lore pages into everything as though it's official?

                    Kind of disappointing that my +7 dark claymore with 20 str 12 dex 30 int 30 faith does 498 AR, but +4(+8) onyx blade does 423. I know there's the +145 fire damage, but that still doesn't really make it work it. Except the sword length but that's about it.

                      just an extra bit of info, it doesnt cost stamina but you can't use it if you have no stamina (cause why not)

                        Hello! Maybe that's just a bug, I don't know, but it looks like this sword weapon art can hit twice people in high/mid range, one with the flame the other one with the buffed sword. I fought an invader, my heavy attack dealt him about half of his life, and I touched him with WA while he was rolling, he took two hits and it put more than half of his life on damages.
                        Also sometime, I only touch people with the end of the weapon art and it deals them between 100/150 damages, I guess the flame deals only the buff damages.
                        If someone has better information about how it works, it would be pretty nice for me!

                          It kicks ass in early level rush, when you get it at level 30's . The weapon art 145 flame dmg is too overpowered in early levels. Not as great in late game pvp though.

                            Fixed mistakes on elfriede's blackflame. It adds a flat 145 fire damage, that does not scale off stats or weapon AR, regardless of weapon upgrade level. it does not apply a % increase

                              creating builds on your own isn't that hard if you know and accept the basics. first of all you need to decide what weapon you build around. Find out what infusion, what stats pushes the damage most. Invest until you get to the hard cap. after that invest in health and stamina. Then you can fiddle arond a bit if you sacrifice a bit of health or power for a spell (ToD) or to avoid fatrole. Your build is complete now. And always keep in mind if your builds aren't viable for pvp they are not viable at all.

                                Nice weapon to grab for an early game pyro since it scales off your casting stats until you get Dark/Chaos infusions. You're probably not using Twinkling Titanite for anything at that point, and if Vilhelm gives you trouble at a low level just grab the Astora GS and cheese him with knockdowns/gravity.

                                  The weapon is cool and decent, however it have too much problems. At 14/12/40/40 this weapon have 152 physical Ar and 368 dark Ar. Too low for PvP. The buff give 145 fire ar, giving a very low buff in PvP.

                                  With dark clutch ring this weapon reach 152 + 423 + 145. Low overall damage. A damage buff Like deep protection or sacred oath is needed.

                                    the WA attack scales with int/fth. i upped int from 17 to 20 and the damage went from 325 to 331 against fire keeper.

                                        With its poor scaling and relatively low damage, I feel like this weapon is best used with higher SL builds that can spare heavy investment into 4 stats, getting the most out its potential. I have a sick SL 300 Spellsword Elric of Melnibone fashion that literally slays with this weapon.

                                          At 14 Str, 12 Dex, 40 Int, 40 Faith this weapon has 520 dmg and buffed with WA its has 665 dmg. I do a Vilhelm cosplay and use it with dark hand (rarely land it) and Filianore Chime or Canvas Talisman with Vow of Silence and Great Geal. Perfect for invasions (because you can stay alive with the heal) and 3vs3 are a win everytime.

                                            You can hit enemies with the activation of the WA, in a short distance in front of you. If they are just within range, it'll do a small amount of damage, I'm assuming fire damage, and if close up it hits with almost a full buffed R1 strike worth of damage. I mainly use it to KO a charging weaker enemy while buffing my weapon at the same time.

                                              I really want to like this weapon, but i just cant. The damage buff doesnt last long enough and its damage just seems kinda low. Sure its not upgraded but i do better damage with a Dark Buff and other weapons which also offer the option for different buffs. The weapon looks cool, but thats about it.
