• You don’t need to breathe, and you don't need to sleep. You can finish a long rest in 4 hours, but must spend those 4 hours in a motionless sleep.

• You have advantage on death saving throws.

Headless: Your head and your body are permanently separated. You gain the following effects:

• You can attach and detach your head using your Object Interaction. Your ability to sever your head prevents you from being killed by decapitation, however, being struck by a critical hit by a weapon attack or unarmed strike causes your head to fly off. Your head lands in a space within 10 feet of you.
• You always know the distance and direction to your head or body unless it is on another plane of existence or if it's blocked by an effect that prevents divination magic.
• Unless your head is being carried by your body or another creature, it can be targeted, its AC being equal to yours but without the benefit of Dexterity or armor that does not include a helmet. You cannot be damaged twice by an area of effect due to this. Your head automatically fails Dexterity saving throws.
• When separate, your body can see and hear so long as your head can see the body. If your head's vision is obscured, your body gains 10 feet of blindsight.
• Your headless body cannot speak but it can consume food and drink as well as cast spells, even spells with verbal components as long as the separated head is not silenced or gagged.
