Onyx Blade Ds3

I can tell you the Onyx Blade is one of those hidden gems that’s totally worth the hunt. You'll find it in the 'Ashes of Ariandel' DLC, specifically in the Corvian Settlement. From the bonfire, head past the bridge where the giant wolf attacks, then drop down into the ruined buildings. There’s a tower with a ladder—climb it, and you’ll find a NPC named Vilhelm. Defeat him, and the Onyx Blade is yours.

This weapon is a beast for dark builds, scaling with both intelligence and faith. Its weapon art buffs it with dark damage, making it perfect for pyromancers or dark spellcasters. The area itself is tricky, though, with those creepy Corvian knights lurking around. Pro tip: Bring a shield with high stability or learn to parry—Vilhelm hits hard but is manageable if you stay calm. The Onyx Blade’s sleek design and lore ties to the Sable Church of Londor make it a favorite among lore hunters too.

Honestly, the 'Onyx Blade' in 'Dark Souls 3' always felt like one of those weapons that sits a little outside the usual sword archetypes — it’s a hybrid weapon with physical plus dark damage and it rewards investment into the right stats rather than raw upgrade numbers. From what I’ve seen playing and poking at item screens, the base attack at +0 is middling for a unique sword: it has moderate physical AR with a secondary dark component that makes it good for bypassing some resistance checks. The important part is the scaling: it starts with low scaling in Strength and Intelligence (usually Ds or Cs at +0) and grows significantly as you upgrade the blade. By mid-upgrade (+5 or so) those Ds/Cs often jump to C/B, and at max (+10) you typically see B or even A in the primary scaling stat, with the dark split staying consistent.

I like to think of it as a quality/intelligence hybrid — it doesn’t compete with dedicated pure-strength greatswords for raw physical damage, nor with full-sorcery catalysts for casting, but with a roughly even spread between physical and dark it becomes deadly for Faith/Int builds or quality builds that want a dark edge. Infusions and Ashen Estus choices can tilt it more toward magic or physical playstyles. For exact numerical ARs, the game’s item screen shows the detailed breakdown and the scaling letters; in practice I check the actual AR after applying my stat levels and upgrades to judge whether it hits damage soft caps for my build. If you want, I can walk you through the math on how the scaling letters translate into extra AR for a specific Strength/Intelligence spread.

The 'Onyx Blade' in 'Dark Souls 3' is one of those weapons that just oozes style and power, especially if you're into hybrid builds. This greatsword scales with both Intelligence and Faith, making it perfect for pyromancers or dark magic users. Its base moveset is similar to other greatswords, featuring horizontal slashes for crowd control and a strong vertical chop for single targets. The weapon art, 'Elfriede’s Blackflame,' is where it truly shines—it buffs the blade with dark fire, adding extra damage and a cool visual effect.

One thing I love about the 'Onyx Blade' is its versatility. The R2 attacks have decent range, and the rolling R1 is quick enough to catch opponents off guard. The buff lasts a solid 45 seconds, so you can pre-buff before engaging. It’s also surprisingly lightweight for a greatsword, letting you stay mobile. Pair it with the 'Prisoner’s Chain' or 'Ring of Favor' for extra survivability. If you’re looking for a weapon that balances raw power and dark aesthetics, this is it.

I can confidently say the 'Onyx Blade' is a hidden gem for Pyromancer builds. This greatsword scales primarily with Intelligence and Faith (both at C), making it ideal for hybrid casters. The base damage is respectable, but the true magic happens when you buff it—its Weapon Art, 'Queen's Darkflame,' adds a hefty 145 fire damage for 45 seconds. The scaling isn’t as aggressive as pure physical weapons, but the split damage (physical and dark) and the buff make it devastating in PvE and PvP if you build around it.
One thing to note is that its scaling doesn’t improve much beyond 30 Int/Faith, so soft-capping at those stats is efficient. It’s also lightweight for a greatsword, allowing for more flexibility in armor choices. If you’re running a 30/30 Int/Faith build, this weapon outperforms many others in its class, especially against enemies weak to dark or fire. Just be mindful of foes with high dark resistance—it can feel a bit lackluster there.

Man, I used to hunt down weird weapons for hours back in 'Dark Souls III', and the Onyx Blade always felt like one of those things that either drops from a boss soul or hides behind a very specific condition. From everything I dug up in my own notes and from the item description in-game, the Onyx Blade is not a regular vendor stock — it’s tied to a boss/unique source rather than being sold by a normal merchant. If you want it, the fastest route is to look at the weapon’s in-game description (open your inventory and check the lore text) because it usually hints whether it’s a drop, a chest find, or made by transposing a boss soul. In my case I checked Ludleth’s transposition menu a lot when I was hunting unique boss weapons, because he’s the guy who turns boss souls into weapons if that’s the path the item takes.

If you don’t want to go spelunking through menus, check a solid wiki like the 'Dark Souls III' wiki or Fextralife — they list the exact source (which boss or chest) and whether any particular NPC will sell it after certain conditions. I’ve posted my own farming route in forums before: check the equip/move list and then confirm the source on a wiki; saves you tons of time compared to blind farming. Happy hunting — if you tell me where you are in the game I can suggest the most efficient place to check first.

Man, I've been messing around with the Onyx Blade in 'Dark Souls 3' for ages and I can say straight up: it’s totally playable on either build, but it rewards different styles. If you lean into Strength you'll feel the weight and raw stagger — it likes to make enemies wobble and it hits like a truck when you two-hand or stack buffs. I usually pump enough Strength to meet its requirements, slap on a Heavy or Refined infusion if the weapon allows it, and pair it with a ring or two that boost physical damage. That gives you big hits and reliable poise damage in most PvE fights.

On the flip side, if you're a Dex fan, you can still make the Onyx Blade work, but it forces a more surgical approach. A Sharp or Refined infusion (again, only if the weapon is infusable) plus Dex investment turns it into something with faster follow-ups and better scaling with dexterity—less raw blunt force, more swift punishing combos and riposte setups. I like to mix in quickstep/roll punishes and weapon arts that lengthen reach. In PvP it’s a mixed bag: Strength builds tend to win trades, Dex builds win at spacing. Personally, I experiment with both and end up favoring Strength for invasions and Dex for duel-focused, mobile playstyles — try both and see which fits how you enjoy skirmishes.

the Onyx Blade is a weapon that stands out for its unique blend of aesthetics and practicality. The weapon’s dark flame buff not only looks cool but adds significant fire damage, making it a solid choice for hybrid builds focusing on pyromancy. Its moveset is versatile, with a greatsword’s sweeping attacks that can catch multiple opponents in invasions.

However, the Onyx Blade does have drawbacks. Its range is slightly shorter than other greatswords like the 'Claymore,' and the buff duration is limited, requiring careful timing. In high-level duels, experienced players can exploit its slower recovery frames. That said, if you enjoy a mix of spellcasting and melee, the Onyx Blade’s burst damage potential makes it a fun and viable option for both invasions and casual duels.

' I can confidently say the 'Onyx Blade' is one of the most visually striking and functionally unique greatswords in the game. Its weapon art, 'Elfriede’s Blackflame,' is a spectacle to behold. When activated, it engulfs the blade in dark fire, significantly boosting its damage output for a limited time. This buff not only adds extra dark damage but also extends the weapon’s reach slightly, making it deadly in both PvE and PvP scenarios.

The 'Onyx Blade' is a favorite among hybrid builds, especially for those investing in both intelligence and faith. The weapon art’s animation is smooth, and the dark flames add a layer of intimidation during invasions. What’s even better is that the buff persists through rolls and swaps, giving players tactical flexibility. Pair this with its innate dark damage and scaling, and you’ve got a weapon that’s perfect for punishing overconfident foes. Just remember, the buff lasts about 45 seconds, so timing is key to maximizing its potential.

I can confidently say the Onyx Blade is one of the most versatile weapons for a pyromancer hybrid. The key stats to focus on are Faith and Intelligence, both at 40, to maximize its dark damage scaling. Strength should be around 16 to meet the minimum requirement, while Dexterity can stay at 12. Vigor and Endurance are crucial too—aim for 30-35 Vigor to survive hits and 25-30 Endurance for stamina management.

Attunement is another important stat, around 24-30, to ensure you have enough FP for pyromancies like 'Black Flame' or 'Great Chaos Fire Orb,' which complement the Onyx Blade's playstyle. The weapon's unique buff, 'Blade of the Dark,' adds significant dark and fire damage, so pairing it with pyromancies creates a devastating combo. Armor-wise, go for something with decent poise and fire resistance, like the Black Iron set, to balance defense and mobility.

Okay, let me gush for a minute — the Onyx Blade in 'Dark Souls III' feels like a weapon that sits between two personalities. It isn't twitchy like a straight sword nor lumbering like an ultra greatsword; it swings with deliberate intent. When I use it, I notice its horizontal arcs have a nicer reach and a weight that makes each hit feel meaningful, so it punishes sloppy spacing from opponents who expect a light-sword rhythm.

Mechanically, the moveset plays out as a hybrid: you get solid R1 strings that aren't super-fast but chain smoothly, and the R2s tend to be chunkier, often trading well because of that reach. Its rolling and backstep R1s catch people trying to poke at close range; I often bait a roll and then follow up with a horizontal R1 to clip their recovery. Compared to a straight sword, you give up some speed but gain more satisfying range and poise pressure; compared to a greatsword, you keep more agility while still landing heavier hits.

Beyond pure moves, the weapon art is the secret sauce — it adds zoning or an extra hit that changes how you approach fights. In casual duels I mix a few swings with weapon-art feints to keep folks guessing, and in PvE it shreds enemies that cluster because the arcs connect well. If you like a sword that rewards thoughtful spacing and timing rather than pure button-mashing, the Onyx Blade is a really fun middle ground.
