Arcane is the Bloodborne build that comes closest to playing a mage. It powers the hunter tools, which function like spells, and it lets you convert weapons to elemental damage and wield the game's most spectacular arcane weapons. It has the steepest learning curve of any archetype, but it rewards that investment with unmatched versatility in the late game.
Bloodborne released in 2015 and has not changed mechanically in years, so the details here are stable. I cross-checked the specifics against the Bloodborne Wiki on Fextralife, the Fandom Bloodborne Wiki, and the r/bloodborne community, all checked in October 2026. Where an exact numeric value could mislead, I have kept it qualitative and pointed you to verify it in-game or on the wiki.
What Arcane actually scales
The Arcane stat does several things at once, which is what makes it both powerful and confusing. It scales weapons that deal arcane or elemental damage, it increases the damage of fire and bolt effects, and most importantly it powers the hunter tools, Bloodborne's equivalent of spells. It also boosts item discovery to a degree. Because Arcane touches so many systems, a high-Arcane hunter has an unusually large toolbox.
There are a few soft breakpoints that matter. Many hunter tools have minimum Arcane requirements, and some scale dramatically as your Arcane climbs, so investing heavily is what separates a dabbler from a true arcane hunter. Unlike a Strength or Skill build, where you simply swing a weapon, an Arcane build is about managing resources, specifically the Quicksilver Bullets that most tools consume, and positioning to land your ranged damage.
This resource management is the heart of the build. Tools cost bullets, bullets are finite in a fight, and so an arcane hunter has to weave tool casts between melee attacks rather than spamming them. Getting that rhythm right is the skill ceiling of the archetype.
The hunter tools: Bloodborne's spells
The hunter tools are what make Arcane feel unique. Augur of Ebrietas unleashes a short-range burst of writhing tentacles, excellent for close pressure and stagger. A Call Beyond fires a spray of homing arcane projectiles and is devastating at the right range, though expensive in bullets. Executioner's Gloves summon tracking skulls, the Choir Bell and Beast Roar offer utility, and the Old Hunter Bone enables a quickstep dash that is useful on any build.
Each tool consumes Quicksilver Bullets, so an arcane hunter needs to manage that pool carefully, using Blood Bullets to supplement when needed. The tools scale with Arcane, so the same A Call Beyond that is mediocre at low Arcane becomes a boss-melting option at high Arcane. Learning which tool fits which situation is the day-to-day craft of the build.
Elemental weapons and conversion
Arcane hunters have two ways to deal melee damage. The first is to wield weapons that natively scale with Arcane, led by the iconic Holy Moonlight Sword from the DLC, which fires moonlight beams, and the Tonitrus, which adds bolt damage. The second, and the real magic of the build, is conversion: using the right blood gems, you can convert a normal weapon's physical damage into fire, bolt, or arcane damage so that it scales with your Arcane stat instead.
Conversion is what gives Arcane its legendary flexibility. With a set of elemental gems, many of the game's best weapons can be made to work for an arcane hunter, letting you tailor your melee to the enemy in front of you, since some foes resist physical damage while others crumble to fire or bolt. This adaptability is unique to Arcane and is why dedicated players consider it the richest build in the game.
The signature arcane weapon, though, is the Kos Parasite. Equipped with the Milkweed rune, it transforms your attacks into writhing tentacle strikes that scale enormously with Arcane, delivering some of the highest arcane damage available. It is the capstone of a pure Arcane build and a goal worth working toward.
Stat priorities for an Arcane hunter
A dedicated Arcane build pours heavily into the Arcane stat, often to a high value, because the tools and arcane weapons scale so strongly with it. You still need Vitality for survivability and Endurance for stamina, and a modest amount of Strength or Skill to meet the minimum requirements of your chosen melee weapon. Beyond those requirements, extra points in Strength or Skill are wasted on an elemental-converted weapon, since the weapon scales with Arcane once converted.
This is why Arcane is unforgiving of indecision: you commit to Arcane and only meet weapon stat minimums elsewhere. Because there is no respec, plan the build out before you start leveling, and be sure of the weapons you intend to use so you know their requirements.

Gems for an Arcane build
Gems make or break an Arcane build more than any other. To convert a weapon to elemental damage you need gems that add fire, bolt, or arcane damage, and ideally a full set so the conversion is complete and strong. Deep and cursed Chalice Dungeons are where the best elemental gems live, so Arcane players tend to be heavily invested in the dungeon grind. Our blood gems guide explains the shapes and effects you will be hunting for, and it is essential reading before you commit to an arcane setup.
Because an arcane hunter often keeps multiple converted weapons for different damage types, you may end up maintaining several gem sets, which is a large but rewarding project. The payoff is a hunter who can answer almost any enemy with the right element.
Managing your bullets and casting rhythm
More than any other build, an Arcane hunter lives on Quicksilver Bullets, because most hunter tools consume several per cast. Your carried bullet pool is limited, so you cannot simply spam A Call Beyond at every threat. The key supplement is the Blood Bullet, a feature that lets you convert a portion of your health into a handful of extra Quicksilver Bullets on the spot. Learning to top up with Blood Bullets at safe moments, and to pick up the bullets enemies drop, is what keeps an arcane hunter firing through a long boss fight.
Arcane combat is a rhythm of weaving tool casts between melee attacks rather than standing back and casting constantly. You close in with a converted weapon, create space, fire a tool into the opening, then reset. Runes that raise your maximum Quicksilver Bullet count are therefore among the most valuable things an arcane hunter can equip, and managing that resource well is the true skill ceiling of the build.
Where Arcane shines and where it struggles
Arcane's flexibility is at its best against enemies with a clear elemental weakness, and the late-game kin enemies in particular often fold to the right element. Because you can carry weapons converted to different elements, or swap gems at a lamp, you can tailor your damage to whatever the area throws at you in a way no physical build can match. This adaptability is the whole argument for the build.
The flip side is that Arcane is weak and awkward early, before you have the Arcane investment, the elemental gems, and the tools to make it hum. A fresh arcane hunter often feels underpowered through the opening hours, which is why the build is recommended as a second character or for players willing to push through a slow start. Once it comes online in the mid-to-late game, though, few builds are as satisfying or as versatile.
Two more practical notes round out the build. First, the item-discovery boost that comes with a high Arcane stat is a genuine side benefit, making an arcane hunter slightly better at farming rare drops, which pairs nicely with the fact that this build already spends so much time in Chalice Dungeons hunting gems. Second, not every tool is a boss-nuke; some, like the short-range burst options, are better treated as fast-casting pressure tools you fire point-blank after a dodge, while the expensive long-range sprays are reserved for the big openings. Mixing a cheap tool for everyday use with one expensive tool for punishing a boss's recovery is far more sustainable than leaning on a single costly option. Because the build is so gear-dependent, keep an eye out for arcane-scaling weapons and elemental gems throughout your playthrough rather than waiting until the endgame, so your hunter is already partway assembled by the time Arcane truly comes into its own. An arcane hunter who has been quietly stockpiling the right gems will feel the build switch on much earlier than one who leaves everything to the final hours.
Shortcutting the setup if you own the game
An Arcane build depends on specific gems and tools that take real time to gather. If you own Bloodborne and want to experience the build without the grind, the store offers a Bloodborne modded save and a max Blood Echoes and consumables package, both on the Bloodborne page. They are a convenience for existing owners curious about the build, not a substitute for learning to pilot an arcane hunter well.
