Dullahan do not need to sleep. Instead, they enter a dormant state and remain semiconscious for 4 hours a day. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep

Your head and your body are separated, the wound that separated them never healing, although you may always attach or detach your head at will as an action. While your head is attached, a critical hit can forcibly detach your head and send it rolling up to 10 ft. away from you. While your head is separated from your neck, you gain the following effects:

• You cannot be killed by decapitation.
• You always know the distance and direction to your head unless it is on another plane or if an effect prevents divination magic it will also prevent this effect.
• Unless your head is being carried by you 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, both head and body can see and hear.
• 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.

Your Unseelie nature has granted you several spells.

• You know the Toll the Dead cantrip
• At 3rd level, you can cast Find Steed once per long rest. The mount conjured is considered fey. Additionally, the steed can be stored in your shadow as an action and retrieved as a bonus action.
• At 5th level, you can cast Knock once per long rest.

You have vulnerability to bludgeoning, piercing, and slashing damage from gold plated weapons. If you are carrying or touching anything made of gold make a DC 15 Constitution saving throw or release the item. Repeat this save every turn you carry the gold.
