Bloodfiend's Arm — Best Heavy Arcane Weapon

Requirements: Strength - 28 / Dexterity - 11 / Arcane - 16
The Bloodfiend's Arm completely changes the traditional idea of what an Arcane build looks like.
Instead of relying on rapid attacks, this Colossal Weapon delivers enormous individual hits and powerful charged Heavy Attacks. It can also change its affinity, allowing it to take advantage of different Arcane-oriented setups.
Its combination of huge raw damage, status potential, stance pressure, and strong Arcane synergy makes it one of the standout DLC weapons for Arcane characters.
The high Strength requirement means it fits best on a STR/ARC hybrid, although two-handing can reduce the amount of actual Strength investment required.
Location: Dropped by Bloodfiends wielding the weapon in Prospect Town and other areas of Shadow of the Erdtree.
Bloody Helice — Best Pure Arcane Duelist Weapon

Requirements: Strength - 16 / Dexterity - 19 / Arcane - 17
The Bloody Helice is one of the strongest weapons for a melee-focused Arcane character.
Its Arcane scaling contributes both to its Physical damage and Blood Loss buildup, making additional Arcane particularly valuable. At high Arcane investment, it can achieve excellent damage without requiring an equally large Dexterity investment.
Its defining feature is Dynast's Finesse, an evasive backward movement with invincibility frames that can transition into a powerful lunging counterattack.
This gives Bloody Helice a more reactive playstyle than most status weapons, rewarding good timing rather than simply attacking as quickly as possible.
Location: Found in a chest after defeating the Sanguine Noble beneath Writheblood Ruins in Altus Plateau.
Ancient Meteoric Ore Greatsword — Best STR/ARC Unique Weapon

Requirements: Strength - 35 / Dexterity - 10 / Arcane - 19
The Ancient Meteoric Ore Greatsword is one of the best additions to Strength/Arcane builds from Shadow of the Erdtree.
It deals Physical and Magic damage, with Arcane contributing to both damage types. This allows even heavily Arcane-focused characters to achieve excellent Attack Power.
Its Unique Skill, White Light Charge, launches you forward at high speed before allowing a follow-up explosion. This gives a normally slow Colossal Sword surprisingly strong mobility and burst damage.
The 35 Strength requirement is substantial, but two-handing reduces the Strength investment necessary to wield it effectively.
Location: Obtained from the altar at the end of Ruined Forge of Starfall Past in Scadu Altus.
Eleonora's Poleblade — Best DEX/ARC Multi-Hit Weapon

Requirements: Strength - 12 / Dexterity - 21 / Arcane - 19
Eleonora's Poleblade combines Physical and Fire damage with innate Blood Loss and an extremely aggressive Twinblade moveset.
Arcane is particularly valuable because it contributes to both Physical and Fire damage while also increasing the weapon's Blood Loss buildup.
Its Unique Skill, Bloodblade Dance, performs a rapid sequence of attacks before creating distance, making it excellent for triggering Bleed and successive-attack bonuses.
It requires more Dexterity than a pure Arcane character naturally wants, so it is best suited to a dedicated DEX/ARC hybrid.
Location: Dropped by Eleonora, Violet Bloody Finger, at the Second Church of Marika in Altus Plateau.
Putrescence Cleaver — Best Arcane/Frost Weapon

Requirements: Strength - 28 / Dexterity - 10 / Arcane - 15
The Putrescence Cleaver is a DLC Greataxe dealing Physical and Magic damage while also carrying innate Frostbite buildup.
Arcane is extremely valuable because it contributes to both of the weapon's damage types, allowing a heavily Arcane-focused build to achieve excellent raw damage.
However, there is an important distinction: its Frostbite buildup does not scale with Arcane. The buildup remains fixed regardless of your Arcane investment or weapon upgrade level.
Its Unique Skill, Spinning Guillotine, provides an aggressive multi-hit attack that can be extended with additional inputs.
Location: Obtained by exchanging the Remembrance of Putrescence after defeating the Putrescent Knight in Shadow of the Erdtree.
Obsidian Lamina — Best DLC DEX/ARC Scythe

Requirements: Strength - 12 / Dexterity - 25 / Arcane - 17
The Obsidian Lamina provides Arcane builds with a unique Scythe built around mobility, Bleed, and evasive counterattacks.
Its Unique Skill, Dynastic Sickleplay, combines evasive movement with sweeping follow-up attacks, creating a fluid hit-and-run playstyle.
The relatively high Dexterity requirement makes it unsuitable for our pure Arcane progression without adjustment, but it is an excellent endgame weapon for a DEX/ARC hybrid.
Location: Obtained near the end of Sir Ansbach's questline in Shadow of the Erdtree.
Rivers of Blood — Best Accessible DEX/ARC Katana

Requirements: Strength - 12 / Dexterity - 18 / Arcane - 20
Rivers of Blood remains a strong Arcane weapon even though it no longer dominates Elden Ring the way it once did.
It deals Physical and Fire damage, has innate Blood Loss, and uses the Unique Skill Corpse Piler to perform an extended sequence of blood-infused slashes.
Its combination of range, Bleed pressure, and relatively manageable requirements makes it a strong DEX/ARC option.
However, it should be treated as one strong Arcane weapon rather than the default answer to every Arcane build.
Location: Dropped by Bloody Finger Okina at the Church of Repose in the Mountaintops of the Giants.
Marais Executioner's Sword — Best Skill-Focused STR/ARC Weapon

Requirements: Strength - 24 / Dexterity - 14 / Arcane - 23
The Marais Executioner's Sword is another excellent Arcane weapon that doesn't rely on Bleed.
Its Unique Skill, Eochaid's Dancing Blade, launches the Greatsword forward while rapidly spinning, potentially hitting an enemy many times during a single cast.
This makes it extremely powerful when combined with successive-attack bonuses and Skill damage buffs.
Because of its Strength requirement, it naturally fits a STR/ARC hybrid, while Arcane contributes strongly to the weapon's mixed damage.
Location: Dropped by Elemer of the Briar in the Shaded Castle.
Ripple Crescent Halberd — Best Pure Arcane Utility Weapon

Requirements: Strength - 12 / Dexterity - 12 / Arcane - 20
The Ripple Crescent Halberd has exceptionally strong Arcane scaling, eventually reaching S scaling in Arcane.
What makes it especially interesting is that it can still be buffed despite its innate Arcane scaling. Arcane can increase applicable Blood Loss, Poison, and Sleep buildup from weapon buffs, giving the Halberd excellent status versatility.
Scarlet Rot is an exception: Rot buildup does not scale with Arcane.
Its excellent reach and low STR/DEX requirements make it particularly attractive for a character following the pure Arcane progression.
Location: Dropped by Second-Generation Albinaurics wielding the weapon, including those found in Liurnia, Mohgwyn Palace, and the Consecrated Snowfield.
Honorable Mentions
Morgott's Cursed Sword — Excellent DEX/ARC Curved Greatsword with a powerful Unique Skill, but its 35 Dexterity requirement pushes it heavily toward a dedicated hybrid build.
Mohgwyn's Sacred Spear — Still an extremely powerful STR/ARC weapon with Blood Loss and excellent AoE through Bloodboon Ritual, although its slower Great Spear playstyle is more specialized.
Flowerstone Gavel — Excellent Arcane-scaling DLC weapon with a ranged Unique Skill that can reduce an enemy's Lightning Damage Negation. Particularly interesting for Arcane/Dragon hybrid characters.
Poisoned Hand — A DLC Fist weapon designed around Poison that provides another way to build Arcane around something other than Bleed.
Ripple Blade — Similar to Ripple Crescent Halberd, with huge Arcane scaling and the ability to enhance applicable status buffs. It trades the Halberd's reach for a compact Axe moveset.
Occult Nagakiba/Uchigatana — Some of the simplest and most effective customizable Arcane weapons. Their innate Bleed works naturally with Occult affinity, while customizable Ashes of War provide far more flexibility than unique weapons.
Bloodfiend's Fork — A useful DLC Spear with innate Blood Loss that can change affinity and Ash of War, making it another good candidate for an Occult setup.
