Vampirism

You have been tainted with the curse, or blessing, of vampirism. It takes 1d6 days for you to fully become a vampire, during which you feel ill and become poisoned, even if you have immunity to it, and a lesser restoration spell and similar effects will cure you from the curse. Also you undergo a physical transformation, gaining the following physical characteristics:

• Your skin become as pale as your original coloration would allow. (i.e. if you had light skin, it becomes marble white in colour, tanned skin becomes cappuccino white and so on)
• Your iris changes coloration, into either red, white or it's original colour becomes more vivid, and have an eerie glow, visible through non-magical darkness.
• Your canines elongate, becoming vicious fangs.
• Your facial features overall obtain a macabre beauty, becoming more attractive.
• Your ears become noticeably pointed at the tips, but still shorter than elven ears.
• Your nails harden and polish, lengthening into natural stilettos. You determine their length.

Once fully transformed you become a vampire, gaining the Vampire's Bite special action, Stiletto Claws and Vampiric Nature. Nothing short of a Wish can cure you now.

 Vampiric Nature.

You've become a vampire, a child of night that feeds on the blood of other living beings, a paragon of deadly elegance.

• Your Charisma score increases by 1, you have a darkvision of 60 feet and resistance to necrotic damage.
• Your nose is particularly sensitive to the smell of blood. You have advantage on any Perception that involves the smell of blood.
• A beating heart is music to your ears. You can hear the heartbeats of every living creature in a 30ft. radius, knowing the exact direction from where the sound comes.
• As a vampire, you no longer age.
• You need to feed on humanoid blood. If you don't drink blood every 1d4 days, you gain a level of exhaustion.

 Vampire's Bite.

You can drain blood and life energy from a willing creature, or one that is grappled by you, incapacitated, or restrained.
Make a melee attack against the target. If you hit, you deal 1 piercing damage and 1d6 necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and you regain hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

 Stiletto Claws.

Your nails have lengthened, hardened and sharpened, becoming natural stilettos at your fingertips. They also seems to have gained a natural polish, always looking pristine and glossy.

Your stiletto nails are natural melee weapons, and you can use them to make unarmed strikes. If you hit with them you deal piercing damage equal to 1d4 + your Strength modifier, instead of the normal damage for an unarmed strike. Being naturally afixed to your hands, they have finesse.
