Sentient Magic Items

Some magic items have sentience and personality. Such an item might be possessed, haunted by the spirit of a previous owner, or self-aware thanks to the magic used to create it. A sentient item might be a cherished ally to its wielder or a continual thorn in the side.
Most sentient items are weapons, but other kinds of items can manifest sentience. Single-use items such as potions and scrolls are never sentient.
The GM controls sentient magic items and their activated properties. A bearer who maintains a good relationship with the item can access those properties. If the relationship is strained, a conflict can ensue (see Conflict below).
Sentient Magic Item Traits
When you make a sentient magic item, you create the item's persona much as you would create an NPC, with these exceptions.
Abilities. A sentient magic item has Intelligence, Wisdom, and Charisma scores. Choose the item's abilities, or determine them randomly as follows: roll for each one, dropping the lowest roll and totaling the rest.
Alignment. A sentient magic item has an alignment. Its creator or nature might suggest an alignment. Otherwise, pick an alignment or roll on the Sentient Item's Alignment table.
Communication. A sentient item communicates by sharing its emotions, broadcasting its thoughts telepathically, or speaking aloud. You can choose how it communicates or roll on the Sentient Item's Communication table.
Senses. A sentient item can perceive its surroundings out to a limited range. You can choose its senses or roll on the Sentient Item's Senses table.
Special Purpose. You can give a sentient item an objective it pursues, perhaps to the exclusion of all else. As long as the wielder's use of the item aligns with that special purpose, the item remains cooperative. Deviating from this course might cause conflict between the wielder and the item (see Conflict below). You can pick a special purpose or roll on the Sentient Item's Special Purpose table.

Conflict
When the bearer of a sentient item acts in a manner opposed to the item's alignment or purpose, conflict can arise. When such a conflict occurs, the item's bearer makes a Charisma saving throw (DC 12 plus the item's Charisma modifier). On a failed save, the item makes one or more of the following demands:
Chase My Dreams. The item demands that its bearer pursue the item's goals to the exclusion of all other goals.
Get Rid of It. The item demands that its bearer dispose of anything the item finds repugnant.
It's Time for a Change. The item demands to be given to someone else.
Keep Me Close. The item insists on being carried or worn at all times.
If its bearer refuses to comply with the item's demands, the item can do any of the following:

• Make it impossible for its bearer to attune to it.

• Suppress one or more of its activated properties.

• Attempt to take control of its bearer, whereupon the bearer makes a Charisma saving throw (DC 12 plus the item's Charisma modifier). On a failed save, the bearer has the Charmed condition for hours. While Charmed in this way, the bearer must try to follow the item's commands. If the bearer takes damage, it repeats the save, ending the effect on a success. Whether or not the attempt to control its bearer succeeds, the item can't use this power again until the next dawn.
