Bladebound
A select group of magi are called to carry a black blade—a sentient weapon of often unknown and possibly unknowable purpose. These weapons become valuable tools and allies, as both the magus and weapon typically crave arcane power, but as a black blade becomes more aware, its true motivations manifest, and as does its ability to influence its wielder with its ever-increasing ego.
At 3rd level, the bladebound magus’ gains a powerful sentient weapon called a black blade, whose weapon type is chosen by the magus (see sidebar). A magus with this class feature cannot take the familiar magus arcana, and cannot have a familiar of any kind, even from another class.
Instead of the normal arcane pool amount, the bladebound magus’s arcane pool has a number of points equal to 1/3 their level (minimum 1) plus their Intelligence bonus.
This ability changes the Arcane Pool class feature and replaces the magus arcana gained at 3rd level.
Intelligence: This is the Intelligence score of the black blade. It starts at 10 and increases by 1 for every two levels of the bladebound magus (at 3rd level, 5th level, and so on).
Wisdom and Charisma: As the bladebound magus increases in level, so do the Wisdom and Charisma of the black blade. These abilities start at 6 and increase by 1 for every two levels of magus.
Ego: A black blade starts with an ego of 5, and that ego increases as the blade becomes more powerful, as per Table: Black Blade Progression below. In cases where a wielder and the black blade come into conflict, like any intelligent item, a black blade can attempt to exert its dominance (see Intelligent Items). Due to their flexible and powerful nature, a black blade has a nonstandard ego progression.
Languages and Skills: A black blade starts with Common as a language. As the black blade increases in Intelligence, it manifests knowledge of languages and arcane lore. Upon reaching an Intelligence of 12, it gains a bonus language of the GM’s choice, and gains 1 rank in Knowledge (arcana). Each time the sword gains a bonus to Intelligence, it gains another language and another rank in Knowledge (arcana).
Senses: A black blade is aware of everything around it like a creature that can see and hear. It can be Blinded and Deafened as if it were a creature. They use the saving throws of their magus, even if the magus is not currently wielding the black blade.
Black Blade Arcane Pool: A black blade has an arcane pool with a number of points equal to 1 + their Intelligence bonus.
Alertness (Ex): While a magus is wielding their black blade, they gain the Alertness feat.
Black Blade Strike (Sp): As a Free Action, the magus can spend a point from the black blade’s arcane pool to grant the black blade a +1 bonus on damage rolls for 1 minute. For every four levels beyond 1st, this ability gives the black blade another +1 on damage rolls.
Telepathy (Su): While a magus is wielding or carrying their black blade, they can communicate telepathically with the blade in a language that the magus and the black blade share.
Unbreakable (Ex): As long as it has at least 1 point in its arcane pool, a black blade is immune to the Broken condition. If Broken, the black blade is Unconscious and powerless until repaired. If destroyed, the black blade can be reforged 1 week later through a special ritual that costs 200 gp per magus level. The ritual takes 24 hours to complete.
Energy Attunement (Su): At 5th level, as a Free Action, a magus can spend a point of their black blade’s arcane pool to have it deal one of the following types of damage instead of weapon damage: cold, electricity, or fire. They can spend 2 points from the black blade’s arcane pool to deal sonic or force damage instead of weapon damage. This effect lasts until the start of the magus’s next turn.
Teleport Blade (Sp): As a Standard Action, a magus of 9th level or higher can expend an arcane point from their or their black blade’s arcane pool, and can call their black blade from as far as 1 mile away, causing it to instantaneously teleport to their hand.
Transfer Arcana (Su): At 13th level, once per day, a magus can attempt to siphon points from their black blade’s arcane pool into their own arcane pool. Doing so takes a Full-Round Action and the magus must succeed at a Will saving throw with a DC equal to the black blade’s ego. If the magus succeeds, they regain 1 point to their arcane pool for every 2 points they saps from their black blade. If they fail the saving throw, the magus becomes Fatigued (but can try again). If they are Fatigued, they becomes Exhausted instead. They cannot use this ability if they are Exhausted.
Spell Defense (Sp): A magus of 17th level or higher can expend an arcane point from their weapon’s arcane pool as a Free Action; they then gains SR equal to their black blade’s ego until the start of their next turn.
Life Drinker (Su): At 19th level, each time the magus kills a living creature with the black blade, they can pick one of the following effects: the black blade restores 2 points to its arcane pool; the black blade restores 1 point to its arcane pool and the magus restores 1 point to their arcane pool; the magus gains a number of temporary hit points equal to the black blade’s ego (these temporary hit points last until spent or 1 minute, whichever is shorter). The creature killed must have a number of Hit Dice equal to half the magus’s character level for this to occur.
Magus Arcana: The following magus arcana complement the bladebound magus archetype: arcane accuracy, broad study, dispelling strike, and reflection.
No, nor can you use that feat to add other properties (such as flaming) to the black blade. You can use your arcane pool to temporarily add abilities to your black blade.

A black blade is always a one-handed slashing weapon, a rapier, or a sword cane. The magus chooses the blade’s type upon gaining the blade, and once chosen, it can’t be changed. As a bladebound magus increases in level, their black blade gains power.
A black blade is independently conscious but features some personality traits reflecting its wielder. A black blade always has the same alignment as its wielder and even changes its alignment if its wielder does. The blade typically works toward its wielder’s goals, but not always without argument or backlash. Each black blade has a mission, and while sometimes two or more black blades will work in concert, each mission is singular in purpose (the black blade’s mission is usually up to the GM and the needs of the campaign or the adventure, or a GM can determine the weapon’s purpose randomly using Table: Intelligent Item Purpose). Some black blades are very open about their missions, but most are secretive. Certain sages have speculated that an Invisible hand or arcane purpose moves these weapons.

Black Blades
A black blade is a particular form of intelligent weapon gained by a magus with the bladebound archetype. There are several ways a magus might gain this weapon. Sometimes it just appears among the magus’s possessions, and its origin is a mystery. Other times the magus finds a black blade during an adventure or event of some kind. Sometimes a black blade is passed down generation to generation in an ongoing search for a magus who can unlock its true potential.A black blade is always a one-handed slashing weapon, a rapier, or a sword cane. The magus chooses the blade’s type upon gaining the blade, and once chosen, it can’t be changed. As a bladebound magus increases in level, their black blade gains power.
A black blade is independently conscious but features some personality traits reflecting its wielder. A black blade always has the same alignment as its wielder and even changes its alignment if its wielder does.
