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 4d6 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.
