Magic items sometimes have intelligence of their own. Magically imbued with sentience, these items think and feel the same way characters do and should be treated as NPCs. Intelligent items have extra abilities and sometimes extraordinary powers and special purposes. Only permanent magic items (as opposed to single-use items or those with charges) can be intelligent. (This means that potions, scrolls, and wands, among other items, are never intelligent.) In general, less than 1% of magic items have intelligence.
Intelligent items can actually be considered creatures because they have Intelligence, Wisdom, and Charisma scores. Treat them as constructs. Intelligent items often have the ability to illuminate their surroundings at will (as magic weapons do); many cannot see otherwise.
Unlike most magic items, intelligent items can activate their own powers without waiting for a command word from their owner. Intelligent items act during their owner's turn in the initiative order.
Creating a magic item with intelligence follows these simple guidelines. Intelligent items must have an alignment, mental ability scores, languages, senses, and at least one other special ability. These statistics and abilities can be improved during creation, increasing the item's overall cost. Many of these abilities add to an item's Ego score. Intelligent items with high Ego scores are difficult to control and can sometimes take control of their owner, making them dangerous to possess.
An intelligent magic item has a base price increase of 500 gp. When determining the total value of an intelligent item, add this value to the sum of the prices of all of its additional abilities gained through being intelligent, before adding them to the magic item's base price.
Any item with intelligence has an alignment (see Table: Intelligent Item Alignment). Note that intelligent weapons already have alignments, either stated or by implication. If you're generating a random intelligent weapon, that weapon's alignment must fit with any alignment-oriented special abilities it has.
Any character whose alignment does not correspond to that of the item (except as noted by the asterisks on the table) gains one negative level if he or she so much as picks up the item. Although this negative level never results in actual level loss, it remains as long as the item is in hand and cannot be overcome in any way (including by restoration spells). This negative level is cumulative with any other penalties the item might place on inappropriate wielders. Items with Ego scores (see below) of 20 to 29 bestow two negative levels. Items with Ego scores of 30 or higher bestow three negative levels.
Intelligent magic items possess all three mental ability scores: Intelligence, Wisdom, and Charisma. Each one of these ability scores begins at a value of 10, but can be increased to as high as 20. Table: Intelligent Item Ability Scores shows the cost to increase one of the item's ability scores. This cost must be paid for each ability score raised above 10. For example, an intelligent magic item with a 15 Intelligence, 12 Wisdom, and 10 Charisma would cost at least 2,400 gp more than the base item (including the 500 gp for being an intelligent item).
Like a character, an intelligent item understands Common plus one additional language per point of Intelligence bonus. Choose appropriate languages, taking into account the item's origin and purposes. If the item does not possess speech, it can still read and understand the languages it knows.
Every intelligent magic item begins with the ability to see and hear within 30 feet, as well as the ability to communicate empathically with its owner. Empathy only allows the item to encourage or discourage certain actions through urges and emotions. Additional forms of communication and better senses increase the item's cost and Ego score, as noted on Table: Intelligent Item Senses and Communication.
Empathy (Su): Empathy allows the item to encourage or discourage certain actions by communicating emotions and urges. It does not allow for verbal communication.
Speech (Su): An intelligent item with the capability for speech can talk using any of the languages it knows.
Telepathy (Su): Telepathy allows an intelligent item to communicate with its wielder telepathically, regardless of its known languages. The wielder must be touching the item to communicate in this way.
Senses: Senses allow an intelligent magic item to see and hear out to the listed distance. Adding darkvision or blindsense allows the item to use those senses out to the same range as the item's base senses.
Read Languages (Ex): The item can read script in any language, regardless of its known languages.
Read Magic (Sp): An intelligent magic item with this ability can read magical writings and scrolls as if through read magic. This ability does not allow the magic item to activate scrolls or other items. An intelligent magic item can suppress and resume this ability as a free action.
Each intelligent item should possess at least one power, although more powerful items might possess a host of powers. To find the item's specific powers, choose or roll on Table: Intelligent Item Powers. All powers function at the direction of the item, although intelligent items generally follow the wishes of their owner. Activating a power or concentrating on an active one is a standard action the item takes. The caster level for these effects is equal to the item's caster level. Save DCs are based off the item's highest mental ability score.
Some intelligent items have special purposes that guide their actions. Intelligent magic items with a special purpose gain a +2 Ego bonus. An item's purpose must suit the type and alignment of the item and should always be treated reasonably. A purpose of “defeat/slay arcane spellcasters” doesn't mean that the sword forces the wielder to kill every wizard she sees. Nor does it mean that the sword believes it is possible to kill every wizard, sorcerer, and bard in the world. It does mean that the item hates arcane spellcasters and wants to bring the local wizards' cabal to ruin, as well as end the rule of a sorcerer-queen in a nearby land. Likewise, a purpose of “defend elves” doesn't mean that if the wielder is an elf, he only wants to help the wielder. It means that the item wants to be used in furthering the cause of elves, stamping out their enemies and aiding their leaders. a purpose of “defeat/slay all” isn't just a matter of self-preservation. It means that the item won't rest (or let its wielder rest) until it places itself above all others.
Table: Intelligent Item Purpose has a number of sample purposes that a magic item might possess. If the wielder specifically ignores or goes against an intelligent item's special purpose, the item gains a +4 bonus to its Ego until the wielder cooperates. This is in addition to the +2 Ego bonus gained by items with a special purpose.
A dedicated power operates only when an intelligent item is in pursuit of its special purpose. This determination is always made by the item. It should always be easy and straightforward to see how the ends justify the means. Unlike its other powers, an intelligent item can refuse to use its dedicated powers even if the owner is dominant (see Items Against Characters). The caster level for these effects is equal to the item's caster level. Save DCs are based on the item's highest mental ability score. See Table: Special Purpose Item Dedicated Powers for a list of dedicated powers.
Ego is a measure of the total power and force of personality that an item possesses. An item's Ego score is the sum of all of its Ego modifiers plus an additional bonus for the cost of the base magic item (excluding the cost of all of the intelligent item enhancements). An item's Ego score helps determine whether the item or the character is dominant in their relationship, as detailed below.
When an item has an Ego of its own, it has a will of its own. The item is absolutely true to its alignment. If the character who possesses the item is not true to that alignment's goals or the item's special purpose, personality conflict—item against character—results. Similarly, any item with an Ego score of 20 or higher always considers itself superior to any character, and a personality conflict results if the possessor does not always agree with the item.
When a personality conflict occurs, the possessor must make a Will saving throw (DC = item's Ego). If the possessor succeeds, she is dominant. If she fails, the item is dominant. Dominance lasts for 1 day or until a critical situation occurs (such as a major battle, a serious threat to either the item or the character, and so on). Should an item gain dominance, it resists the character's desires and demands concessions such as any of the following:
In extreme circumstances, the item can resort to even harsher measures, such as the following:
Naturally, such actions are unlikely when harmony reigns between the character's and item's alignments or when their purposes and personalities are well matched. Even so, an item might wish to have a lesser character possess it in order to easily establish and maintain dominance over him, or a higher-level possessor so as to better accomplish its goals.
All magic items with personalities desire to play an important role in whatever activity is under way, particularly combat. Such items are natural rivals, even with others of the same alignment. No intelligent item wants to share its wielder with others. An intelligent item is aware of the presence of any other intelligent item within 60 feet, and most intelligent items try their best to mislead or distract their host so that she ignores or destroys the rival. Of course, alignment might change this sort of behavior.
Items with personalities are never totally controlled or silenced by the characters that possess them, even though they may never successfully control their possessors. They may be powerless to force their demands, but most remain undaunted and continue to air their wishes and demands.
