Your consciousness and soul reside in an animated mechanical body. As such, you are a living creature with some of the benefits and drawbacks of a construct.
Living Construct. You do not eat, drink, or breathe. You can’t drink potions or gain benefits that come from drinking, eating, or inhaling vapors. You do however have a port somewhere on your body that you can inject Crystal Rods. These have different effects on the construct according to type.
Artifical. You are immune to disease, poison damage, and the poisoned condition. You also are not effected by hot or cold weather as if you are adapted. Extream temperatures still effect them.
Maintenance. You do not sleep as normal. During a rest, you must perform maintenance on your gears, springs, and joints, following the normal rules governing rest and activity. While performing this maintenance, you are aware of your surroundings but you have disadvantage on Wisdom (Perception) checks. If you go longer than 36 hours without performing maintenance (you don’t take a long rest), you gain one level of exhaustion.
