Tiny construct, neutral
Damage Immunities poison
Telepathic Bond. While the homunculus is on the same plane of existence as its master, it can magically convey what it senses to its master, and the two can communicate telepathically.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 1 piercing damage, and the target must succeed on a DC 10 Constitution saving throw or be poisoned for 1 minute. If the saving throw fails by 5 or more, the target is instead poisoned for 5 (1d10) minutes and unconscious while poisoned in this way.
Shaping a mixture of clay, ash, mandrake root, and blood, one can channel rare ritual magic to create a faithful, squirrel-sized companion.
Shared Mind. A homunculus knows everything its creator knows, including all the languages the creator can speak and read. Likewise, everything the construct senses is known to its master, even over great distances, provided both are on the same plane. Functioning as a spy, a scout, an emissary, or a messenger, a homunculus is an invaluable servant for a spellcaster engaged in secret experimentation or adventuring.
