The creature is incapacitated (see the condition), can’t move or speak, and is unaware of its surroundings.
Attack rolls against the creature have advantage.
The creature automatically fails Strength and Dexterity saving throws.
The creature has resistance to all damage.
The creature is immune to poison and disease, although a poison or disease already in its system is suspended, not neutralised.
