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

      Damage is slightly less than what'd you'd get on dark weapons on a dedicated dark build, but the range is excellent, especially on the R2 poke. I use a dark claymore or longsword as a primary, and switch to this for defensive duelists or shorter UGS (zwei, BKGS, CKGS) because the reach gives a definitive edge. Also, the WA can hit people (hyper armour? not sure), making a delicious *****-slap for styling on your opponents.

        So annoying reading stuff like " It is not a good weapon" " To much spit damage better use claymore" stfu. This Weapon looks amazing ! A blade covered in black flames this is awesome ! Still using it. The damage is Ok tbh. Not everyone is into playing Meta. I can highly recommending this weapon. Really fun to use and it looks great, good range and weapon art can combo after R1.

          This weapon scales with 4 stats (better with magical stats), has dark damage and hyper armor. It can go unappreciated only by these level 120 only players.

            Man Saint Riot was right I had to make a build this weapon is really fun. Like its a great sword that BURSTS INTO FLAMES. Like who tf wouldn't want that?

              I'm getting the feeling the "Darkflame" buff was suppose to actually effect "Dark" rather than flat 145AR in Fire. Meaning towards end game Carthus Arc makes this very unimpressive. At 50/30 Str/Dex my Claymore outclassed it. So basically it's a poor Scaling greatsword with innate Dark but the Fire doesn't effectively aid it. Translating to about 70 damage for 45s VS 60s from CFA. I guess it's pretty but there's been Dark Infused options.

                best greatsword choice for lowlevel PVP. well, maybe drakeblood is better with resins. but it's something else besides the stupid dark hand and dragonslayer axe builds, and who doesnt like black fire on their decorative sword?

                  This weapon is absolutely amazing on my dark/pyro character. I carry demon scar in my left hand, and use black flame, black fire orb, and whatever other spell feels necessary at the time, and in my right I use this, a dark followers saber, or a dark murky hand scythe. It’s a very well varied build with lots of ways around any defense. Hand scythe has quick step, saber has fast attacks and the guard break weapon art, and onyx blade splits between physical, dark, and fire, which is great seeing as I use the dark clutch ring and sometimes the fire clutch ring. It’s by far the most overpowered build I’ve ever used. Even capable of taking out zweihander/parry/chaos dagger builds, the most cancer of all. Quickstep of hand scythe combined with guaranteed black flame after an attack from demon scar is amazing. But onyx blade is definitely viable with the right build and the right rings, it outperforms most of the greatsword I’ve infused with dark

                    So I found Out that the WA from this is able to guarantee stunning the twin ultra ringed knights, it will interrupt them no matter what as long as it hits and, as the WA consumes no stamina, you can spam it to stunlock the ringed knight until he is knocked out of range. Not really practical, Just an interesting thing I noticed

                          I really don't care it does less damage than other great swords, it looks beautiful and therefore adds to my fun. min-maxing < creativity. Hex-blade ahoy!

                            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.

                                          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)
