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

Elfriede, the eldest amongst her sisters and leader of the Sable Church, bestowed this sword to her knight.

Only, the sword was a farewell gift, and acceptance signified the knight's resignation from Elfriede's service.

Skill: Elfriede's Blackflame

Enwreath blade with blackflame, born of the similarly-hued flame that smolders within her.

      I haven't uses the Onyx Blade myself and correct me if I'm wrong, but is this not the best greatsword? Minimal strength scaling so one handing is viable, one and two handed have thrusting R2s, its length, and the weapon art is a straight up damage boost. Honestly, one of the harder weapons to fight against.

        This has to be one of the best weapons for anyone running a Dark and/or Fire based build. The damage that is just is just astounding.
        On my character, whom has a 40/40 INT and FTH, with 14/12 STR and DEX, the AR is 520.
        With the Elfriede's Blackflame buff, it rises to 671 (726 with the Dark Clutch ring).

          I'm trying to convert my character into a quality build and was wondering what is better, wolf knight greatsword or the onyx blade? My strength and dexterity are 40. If I get my faith and intelligence up to 40 as well, will it he better than the wolf knight greatsword even though it has split damage, no bonus towards abyssal creatures and hollows, and lower strength and dexterity bonus?

            This weapon makes the enemies in Irithyll of the Boreal Valley practically child's play, considering most/all of the enemies there are weak to either Dark or Fire. It's especially good for taking down the silver knights and makes farming for proof of concords a lot easier.

              I was using this on Champion Gundyr, and oddly enough, it did less damage with the buff than it did without it? I'd like to say it's because it's damage is splitting further, as well as to an element that does less than purely dark to Gundyr, but I'm not entirely sure at this point. Can I get someone to test how the buff interacts with fire defense sometime? I'm on PS4.

                Easily obtainable indeed, just run like a little ***** to the Villheim's fight and if you can't take him down just push him to his death outside the library.

                  I'm thinking dark pyros with dark clutch and parting with up close (dark flame, sacred flame)and normal flame for dark serpent chaos fireball and chaos bed vestiges...and OF COURSE the usual rings (sage swamp witch) and other suggestions?

                  • 29 Nov 2016 06:11  

                    Man if only the weapon art buff added dark damage instead of would be insanely good. Yet another wasted potential or From just going all "muh balance"

                    • 27 Nov 2016 22:18  

                      So, question for all my future pyro-bros. What's better, dark clutch and use dark pyros with either normal flame max or parting flame max? Or fire clutch and constant WA buffs with chaos bed, chaos fireball etc.?

                        Greatswords were fine' such a balanced weapon class, but FROM had to buff the *****ers to oblivion. I hate them, but especially this *****er. It outranges a *****ing glaive for *****s sake.

                          it's has bug along with scholar candle stick
                          when you use onyx blade sword art and switch quickly to scholar and use sword art result is scholar candle stick do onyx blade sword art and vice versa
