Vampire (Stage 1)

     In your travels you've been turned into a creature of the night. Vampires rule the sunless skies. Discuss with your DM if this is something you could've been afflicted with in your backstory. Use this as Stage 1 and talk to your DM about moving on to Stage 2. Upon being afflicted with Sanguine Curse, you will gain 2 boons and 1 flaw.
Vampire Save = 8 + (prof) + DEX modifier.
          -You now have access to Blood Fury Abilities using Fury Points (FP).
You have become possessed by the thirst that grips all vampires. In combat, this thirst drives you into an insatiable frenzy of bloodshed. Whenever you deal combat damage with an unarmed strike or a melee/ranged weapon to a target that can bleed, and is not undead or a construct, you gain 1 Fury Point. You may only have a maximum of 4 FP at any time. Upon completing a short or long rest, they reset to 0. You use these points for certain abilities that you learn throughout your stages.
     -Fanged Bite: (1FP) On your turn, after you take the attack action, you can use your bonus action to make a special unarmed bite attack. You can use DEX instead of STR to hit with this attack. This attack deals 1d4 + DEX/STR piercing damage. The target must succeed on a CON save or take 2d6 Necrotic damage. You regain hit points equal to the necrotic damage dealt this way. This attack generates a Fury Point as normal. If you kill a Medium or smaller creature with this attack, you gain 3 FPs instead.
     -Calculated Strike: (1FP) When you hit with a melee weapon attack, you may this ability before damage is dealt. If you do so, you may add 1d6 of the same damage type to your damage total. Using this ability negates gaining any FP for that attack.
     -Vampiric Mist: (2FP) As a bonus action, you can disappear in a puff of shadowy mist and teleport up to 30ft to an unoccupied space you can see.
     -Unearthly Reflexes: (1FP) After you've rolled a DEX Save, but before the DM determines the result, you can use your reaction and take half damage on a failed, and no damage on a success.
     -Deathly Horror: (3FP) As a bonus action, you can emit a ghastly distortion of your true form. A creature of your choice within 30ft must succeed on a WIS Save or become frightened of you for 1 minute. A creature can repeat the Save at the end of each of their turns, ending the effect on a success.

          -Undead Form. Your DEX increases by 2 and your CHA increases by 1, not to surpass 16 this way. (If your current scores are above 16, you do not benefit from this portion.).
In addition , your creature type changes to Undead rather than Humanoid. Spells that affect Undead of a specific CR have no affect on you.
     If a spell or ability other than your own would cause you to gain Hit Points, you gain temp HP instead. If you are reduced to 0 HP and fall unconscious as a result, any healing you receive will stabilize you and leave you at 1 HP. Furthermore, you cannot die from old age and you do not require air, food, or drink.

     (Flaw) The Sanguine Curse: has taken control of your life. As a result you gain the following features:
          -Forbiddance. You cannot enter a private residence you do not own without permission from one of the occupants. Buildings of commerce or pleasure are acceptable. If you enter a residence involuntary, you take 1d8 psychic damage at the start of your turn while inside.
          -You gain Darkvision out to 60ft. If you already have darkvision, wearing the goggles increases its range by 60 feet.
          -You gain Sunlight Sensitivity, While in Sunlight, you have disadvantage on attack rolls and ability checks that rely on sight.
          -You must feed on fresh blood of a humanoid every 7 days.
