Dullahan

Races that are not Large nor have an innate flying speed gain an extra Feat of their choice. This Feat must be a "Full Feat".

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character. 

You gain 3 ability points to increase any abilities of your choice. You can't increase a single ability by more than 2 with these points.

You may detach your head or reattach it as a free action on your turn. While your head is removed you can see and hear from the head but your body is deafened and blinded and you may use your head as an improvised weapon that deals 1d6 bludgeoning damage and has a thrown range of 60/120. If your head takes or deals any damage or when you finish a long rest, it turns into mist and reappears on your body. You do not suffer any of the damage that your head takes while it is separated. 

When an effect specifically targets humanoids or undead you may choose whether or not it affects you. 

You have Blindsight out to 10ft. If you have blindsight from another source, you instead gain an extra 10ft of blindsight 

You know the toll the dead cantrip. When you reach 3rd level, you can cast the wrathful smite spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the Find Steed spell once with this trait and regain the ability to do so when you finish a long rest. The steed’s creature type is undead rather than the normal options. You can also cast these spells using any spell slots you have. 

You use your Spell Save DC or Mastery Save DC (your choice) for these spells. If you have a class feature that allows you to learn spells, you count these spells as known by that class. You always have them learned or prepared, and they don’t count against the number of spells you can learn or prepare.
