Headless - Your head and your body are separated, the wound that separated them permanently scarred. 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 15 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.

At the end of a short rest or long rest, you can summon your head into your empty hand as long as it is on the same plane of existence

Horrific Aura - You gain access to the thaumaturgy feat, and can gain advantage on a single intimidation roll per long rest when your head is not attached to your body.

Cursed - You can cast Bane Once per long rest

Special Feat: Headless Haunter - Nukekubi
