You are a synthetic being made in the exact shape and design as a kind of living creature, most likely the species that made you. You were either made explicitly to blend in with members of that species, or created with a more stark and technological design. Depending on which species created you, your internal components could be obviously mechanical, or they could appear similar to biological organs.
Ability Score Increase. Your Intelligence score increases by 2, and your Charisma score increases by 1 as well.
Age. Your species does not age. It’s possible you were constructed quite recently, but due to your programming you behave as an adult.
Form. Choose one of the following at character creation:
Intimidating. You have advantage on Charisma skill rolls when interacting aggressively with the species you were designed to emulate. You are proficient in the Intimidation skill.
Simulative. Any skill used to notice that you are not the species you were designed to emulate suffers disadvantage on the roll. You are proficient in the Deception skill.
Inorganic. You do not need to eat, drink, or breathe, and you do not become unconscious when you rest for the night.
Robotic Frame. You have resistance to slashing damage, but suffer vulnerability to electricity damage. You are immune to poison damage and cannot become poisoned.
