The Crimson Sovereign

Your patron is a powerful being who once ruled a forgotten vampire court, long ago consumed by hellfire rather than sunlight. A being of infernal blood magic, they offer you seductive power, sovereignty over the weak, and a thirst that is never quenched.

Whether your patron is a vampire lord devoured by a Fiend, a cursed noble from the Crimson Courts of Hell, or a divine predator of forbidden bloodlines, their gift is clear: you are royalty now—and blood, fire, and fear bow before you.

 

Crimson Boon

Crimson Boon: At level 1, you gain Thaumaturgy as a cantrip. When you deal damage using Vampiric Touch, you regain temporary hit points equal to your Charisma modifier in addition to the normal healing. Additionally, you gain Darkvision out to 60 ft., and if you already have Darkvision, its range increases by 30 feet.

Blood Price. Beginning at level 1, when a creature you can see within 60 feet takes damage, you can use your reaction to mark them with a Blood Sigil for 1 minute (no save).

• Once per turn when you deal damage to a marked creature, you deal additional fire or necrotic damage equal to your Charisma modifier (your choice).
  
  

You can use this feature a number of times equal to your proficiency bonus per long rest.

Level 3: Blood sigil's Embrace 

• Blood Sigil: When you use Blood Price, the mark you place on a creature with the Blood Sigil empowers your blood magic. If you are damaged, you regain hit points equal to the full damage dealt to the marked creature, up to your HP maximum. If you are not damaged, you instead gain temporary hit points equal to half the damage you deal.
  
  
• Crimson Flow: When you damage a creature with the Blood Sigil, you may use a bonus action to Siphon Blood, allowing you to move up to 5 feet without provoking opportunity attacks.

Infernal Hunger

Infernal Hunger

Beginning at level 6:

• Infernal Hunger: You no longer need to eat or drink. Once per long rest, when you reduce a creature with blood to 0 HP, you may do one of the following as a free action:
  
  
• Regain a Warlock spell slot.
  
  
• Gain resistance to all damage until the start of your next turn.
  
  
• Cause nearby enemies within 10 ft. to make a Wisdom saving throw or become frightened until the end of your next turn (DC = 8 + your Cha modifier + PB).

Crimson Veil

Unlocked at level 10: 

Crimson Veil: You can move through dim light or shadows like a phantom. When in dim light or darkness, you can use your bonus action to teleport up to 30 feet to a space in dim light or darkness that you can see. If you appear adjacent to a creature and cast a spell or attack it that turn, you may add your Charisma modifier to the damage of that action (once per turn).

Sovereign Ascendance

Starting at level 14:

You fully embody your patron’s will. Once per long rest, you may activate your Crimson Ascendance for 1 minute. While active:

• Your movement speed increases by 10 feet.
  
  
• You gain resistance to fire and necrotic damage.
  
  
• When you deal damage to a creature, you regain hit points equal to your Charisma modifier (once per turn).
  
  
• You may use Blood Price without expending a use.
  
  

Additionally, you gain the following abilities:

You can cast Dominate Monster once per long rest without expending a spell slot. When you cast this spell, the creature is also affected by your Blood Price feature.

Whenever you reduce a creature with blood to 0 HP, you regain a number of spell slots equal to half your Charisma modifier (rounded up). These slots can be of any level.

You become immune to aging and diseases of time. You no longer need sleep, instead entering a trance-like state for 4 hours a day, remaining fully aware of your surroundings.

Once per long rest, you can activate an aura of Sovereign Wrath as a bonus action. For 1 minute, all creatures that start their turn within 10 feet of you take fire damage equal to your Charisma modifier (minimum 1).
