Your Constitution score increases by 2, and your Strength score increases by 1.

A gargoyle doesn't require air, food, drink, or sleep. When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn't render you unconscious, and you can see and hear as normal.

Though made of stone, gargoyles are deceptively light for their size. Gargoyles stand 5 to 7 feet tall, and average 300 pounds.

Gargoyles excel at lying in wait to ambush unwary foes. You gain proficiency in Deception.

Your stony wings grant you a flying speed of 30 feet. You can still use this speed while wearing armor.

Your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Your stony flesh increases your durability greatly. When you aren't wearing armor, your AC is 13 + your Dexterity modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield's benefits apply as normal while you use your natural armor.

When you take the Hide action, you can become completely still, taking on the appearance of a statue. After you do so, your speed is 0 until the end of the current turn. You are hidden from creatures that do not know your true nature until your true nature is revealed.

A creature that uses its action to examine you can determine your true nature with a successful Intelligence (Investigation) check, opposed by your Constitution (Deception) check, as your physical construction determines how believable your deception is. Your true nature is also revealed to a creature that sees you move.
