DND 5th Edition

Source: Plane Shift - Kaladesh

Prerequisite: Intelligence 13 or higher

You are skilled in the creation of servos—tiny constructs that function as personal assistants. You can cast the Find Familiar spell as a ritual, creating a servo to serve as your familiar instead of an animal. It uses the Servo stat block, but in every other way, a servo familiar functions as described in the find familiar spell.

You can communicate telepathically with your servo familiar and perceive through its senses as long as you are on the same plane of existence. You can speak through your servo in your own voice.

Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your servo familiar to make one attack of its own.
