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.

Notes and Tips:

  • Cannot be Infused but can be Buffed by using the Weapon Art.
  • Damage from the Weapon Art is Fire Damage.
  • Upgrades with Twinkling Titanite.
  • This is the longest Greatsword weapon.
  • Without using the skill, the base damage is increased by the Dark Clutch Ring only.
  • The weapon art lasts 45 seconds and isn't effected by the Lingering DragonCrest Ring

      lot of people seem to say the 'triple split damage' for this weapon. The chart above seems to only say two - physical and dark. What is the third kind? Buff seems like it would buff the dark damage portion of it

        I get this weapon is split damage but doing a crap ton of damage isn't the only thing that matters.. I've *****ed up gankers/triple teamers with this sword. That thrust move is God like and then following up with a 2 hit stun lock with r1 kills most people.. if not roll catching them with another thrust does the trick. Also the WA is actually a decent way to ***** slap people trying to follow your rolls haha

          Does the Leo ring help the R2 pokes as much as say, the hollow slayer? Since it mostly deals dark damage, and I don't know if the Leo ring helps with elemental damage

            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.
