Which Infusion Best Suits The Ds3 Onyx Blade Build?

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.

I can confidently say the 'Onyx Blade' is one of the most versatile weapons for elemental infusion. While it already has innate dark damage, you can infuse it with other elements like fire or chaos to create a hybrid powerhouse. Fire infusion boosts its raw fire damage, making it deadly against enemies weak to flame, while chaos infusion adds fire scaling with intelligence and faith, perfect for pyro builds. The 'Onyx Blade' also shines with dark or deep infusions, further amplifying its dark damage. However, lightning or crystal infusions aren’t as effective since they don’t synergize well with its natural stats. If you’re running a dark or pyro build, this weapon is a dream. Pair it with the right rings and buffs, and you’ll melt through enemies like butter. Just remember, its true potential unlocks when you embrace its dark roots and complement it with fire or chaos for maximum devastation.

If you're gearing the Onyx Blade for duels in 'Dark Souls III', the first thing I tell myself is: pick the role you want it to play. The Onyx Blade can be a jukey, spacing-heavy sword or a heavy-hitting trade machine depending on how you upgrade and what stats you pump. Start by fully upgrading it to +10 at the blacksmith — that’s non-negotiable for PvP; all scaling bonuses and infusion effects are most useful at max upgrade. From there, match the infusion to your stat spread: Heavy if you’re stacking Strength, Sharp if you lean Dex, Refined if you’re splitting Strength/Dex, and elemental or deep infusions if you’re pairing with Faith/Int/hexes. Raw is only for weird low-stat builds and usually not PvP-friendly. Mechanics matter as much as the numbers. Aim your primary offensive stat to the softcap (around 40 for most builds) so the Onyx Blade actually converts that scaling into damage. Don’t skimp on Vigor and Endurance — you need HP and stamina to win trades. Consider boosting equip load so you can wear decent armor without fat-rolling; being able to tank a hit and retaliate with the weapon art or a strong R1 string makes a massive difference. And experiment with weapon buffs or temporary resins if your build supports them — they turn the Onyx Blade into a surprise threat against turtles. On the practical side, work on timing: the weapon art and R2s cover space and create openings, while R1 flurries and mixups punish rolls. Change your approach in each match: sometimes bait a roll and raw punish, other times play spacing and poke until you can commit. I spend a lot of practice time in 1v1 duels testing different infusions and swap a ring or two depending on whether I’m facing heavy armor or glass cannons — small adjustments go a long way. Try a few builds in casual duels, note what opponents struggle with, and lean into that; the Onyx Blade rewards patience and smart reads more than reckless swinging.

Oh man, the Onyx Blade question always gets me excited — I love tinkering with weapon combos. From my time testing weapons in Dark Souls 3, the short version is: most weapon buffs from sorceries and miracles will work on normal melee weapons, so you can cast things like Magic Weapon or Lightning Blade (or even Crystal Magic Weapon) to add elemental damage to a blade. That said, there are a few caveats that matter in practice. I usually check two things before I buff: whether the Onyx Blade already has an innate elemental or unique damage type, and whether I’ve infused it at the blacksmith. If the weapon is already elementally infused, some buffs may overwrite or interact strangely, so the resulting damage split can change and sometimes be less effective than you expect. Buffs consume FP and last a limited time, so for PvE I tend to buff before big fights; in PvP you’ll want to be careful because many buffs are visible and predictable. Personally, I love pairing a caster-friendly sword with a buff that complements my main stat — it feels rewarding to see the damage numbers pop differently based on the buff I chose.

I get a little giddy thinking about ring loadouts for a heavy-swinging Onyx Blade build, because it's one of those weapons that rewards thinking about trade-offs more than pure math. For me the foundation is simple: more raw damage and survivability, plus enough equip load to keep the Onyx Blade moveset intact. That usually means Ring of Blades (or its upgraded versions) for flat physical punch, then a defensive/support ring like Ring of Favor to shore up HP/stamina/equip load. Those two together cover the basics: hit harder, and don't fall over when you get hit. If I’m gearing for a tanky playstyle I slot Havel’s Ring and Prisoner’s Chain (the latter for big HP/stamina/equip load boosts at a cost) so I can wear heavier armor and trade hits. If I want faster rolls and more aggressive spacing, I swap to Chloranthy plus Flynn’s Ring (if my equip load is light enough) — Chloranthy keeps my stamina regen snappy for repeated combos. Hornet Ring is a must if you plan to fish for ripostes and backstabs; it turns those into massive payoff moments. Practical tip: don’t glue yourself to one set. In invasions I’ll carry a tanky set for trading and a light set for hit-and-run. Also remember weapon infusions and Ashes of War can change what rings are optimal — a heavy-infused Onyx Blade leans more into strength rings, while a buffed or hybrid blade nudges you toward more FP/crit support. Play around and swap mid-session; the build’s personality changes a lot with just one ring flip.

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 in 'Dark Souls 3' is such an underrated gem, and I have to say it’s one of my absolute favorites! Personally, I enjoy playing the game with a focus on faith builds because the weapon’s unique scaling with both faith and strength offers some really cool versatility. What I often do is invest heavily in strength—aim for around 40—and then pump faith up to about 30. This lets you capitalize on the weapon’s damage potential while also allowing you to cast some powerful miracles to buff yourself or heal. In terms of stats, stick with a minimum of 14 Dexterity just to wield the sword effectively, but that’s the bare minimum. Once you've got your dex and strength sorted out, it’s all about the armor and rings. I usually go for the Ring of Favor for that added health and stamina boost, paired with the Chloranthy Ring for stamina regeneration so I can keep swinging. Don’t forget to equip the Lightning Clutch Ring to maximize your damage even further when rocking with miracles! What truly makes the Onyx Blade shine are its buffs and attacks. Using it in conjunction with the Lightning Blade spell can really wreck enemies in the game. I’ve had some great moments getting facial expressions from bosses with my combo attacks! Just be wary of your stamina; it can drain quickly if you’re not careful, especially in fights where dodging or rolling is necessary.
