Thin-Blooded

The weakening of Caine’s curse has produced a spectrum of vampires on the edges of what the condition can sustain. Three overlapping categories exist: Caitiff (Clanless), thin-blooded (vitae too dilute to fully function), and the emerging 16th Generation. These are not the same thing — though Kindred rarely bother to distinguish.

Source: Beckett’s Jyhad Diary.

Definitions

Caitiff are Clanless vampires. Any Generation can be Caitiff. They have no Clan weakness or in-Clan Disciplines; instead they choose any three starting Disciplines freely. The Caitiff condition is common but not universal in high Generations.

Thin-blooded suffer from weakened vitae that cannot be used as effectively as normal vampiric blood. A portion of their vitae remains unresponsive when called upon — it still fuels nightly reanimation, but cannot be directed toward powers, healing, or Attribute enhancement. This condition is most common in 14th and 15th Generation. All 15th Generation vampires are thin-blooded. Higher Generations may also exhibit the condition.

The distinction: Thin-blooded is a vitae condition; Caitiff is a Clan condition. A vampire can be both, one, or neither. High-Generation Kindred making no distinction is socially accurate but mechanically imprecise.

Thin-Blooded Mechanics

15th Generation

• Blood pool maximum: 10 (same as standard)
• 4 blood points are inaccessible for powers, healing, or Attribute enhancement — they fuel reanimation only. The remaining 6 points function normally.
• Cannot create blood bonds, Embrace childer, create ghouls, or maintain existing ghouls
• Sunlight inflicts lethal damage rather than aggravated; can attempt to soak with Stamina
• No Clan weakness
• Three starting Disciplines chosen freely; no Discipline may be raised above 2 dots
• Cannot start play with Domain or Status Background
• Gains effects (but not the Merits themselves) of Blush of Health and Eat Food
• Can conceive a Dhampir child

Thickening the blood: A thin-blooded vampire who successfully lowers their Generation through diablerie loses the thin-blooded condition entirely — they gain full use of their vitae, can create blood bonds, Embrace, and create ghouls, but also lose any resistance to sunlight and the capacity for prophecy.

14th Generation

14th Generation vampires are not automatically thin-blooded, but the condition manifests in a significant minority. Treat as thin-blooded on a case-by-case basis at Storyteller discretion. If thin-blooded, apply 15th Generation rules above.

16th Generation (5-Point Flaw)

The 16th Generation exists at the absolute edge of vampiric viability. A character with this Flaw was Embraced within the last year. Their vitae is so dilute that only 4 of their 10 blood points can be used for Disciplines, healing, or raising Attributes. For these functions, they must expend 2 blood points to achieve what a normal vampire achieves with 1. The remaining 6 blood points cannot be directed; rising still costs 1 blood point per night.

Additional restrictions:

• Cannot create a blood bond or Cainite childe
• Cannot create or sustain ghouls
• No Clan weakness; choose three starting Disciplines freely, but no Discipline above 2 dots
• Sunlight inflicts lethal damage; soak with Stamina
• Gains the effects of Blush of Health and Eat Food automatically
• Can conceive a Dhampir child

Note: The 16th Generation is an optional addition to chronicles dealing explicitly with Gehenna-era content.

You Are What You Eat

All Kindred are influenced by the nature of blood they consume, but thin-blooded feel this effect acutely. Feeding exclusively from a particular type of vessel for several consecutive nights can temporarily shift Discipline affinities:

• Feeding from vagrants, the homeless, or street criminals (unseen, marginal people) for several nights may lower difficulty by 1 on Obfuscate rolls while raising difficulty by 1 on Presence rolls
• Feeding exclusively from animals associated with a Gangrel power (bats, wolves, feral cats) may allow temporary access to a single rank-1 Animalism effect even without the Discipline — at Storyteller discretion

This is not mechanical transformation — it is the thin blood responding to its immediate contents more readily than potent vitae would. Effects last only as long as the feeding pattern continues.

Merits and Flaws for Thin-Blooded Characters

These supplement standard V20 Merits and Flaws for characters near or at the thin-blooded spectrum.

Recommended Flaws

Flaws of weakened vitae (from standard V20): Dulled Bite, Flesh of the Corpse, Open Wound, Permanent Wound, Smell of the Grave, Infertile Vitae, Slow Healing

Flaws of the outcast: Sire’s Resentment, Hunted Like a Dog (thin-blooded are persecuted across all Sects)

Flaws of ignorance: Can’t Cross Running Water, Conspicuous Consumption, Lunacy, Repelled by Crosses, Repulsed by Garlic, Stereotype, Vulnerability to Silver (thin-blooded who learned of vampirism from folklore or media may internalize these beliefs to the point of literal susceptibility)

Recommended Merits

Blush of Health, Calm Heart, Deceptive Aura, Early Riser, Eat Food, Inoffensive to Animals, Light Sleeper, Medium, Oracular Ability.

Seer (4-Point Merit)

Requirement: Must have the 15th Generation, 16th Generation, or Thin Blood Flaw.

Many thin-blooded receive involuntary prophetic flashes about the Jyhad. Their weak vitae may trap them in a state between life and unlife, where they perceive the machinations of elders. Some believe this ability stems from having been briefly dead during a delayed Embrace — spending time unbound from the normal flow, accumulating memories of the future.

Effect: You see patterns in faces, air currents, and daytime dreams that reveal information about Cainite affairs. These patterns are symbolic and require interpretation.

Roll: Perception + Occult

Modifiers: Close familiarity with the people involved, or a recurrence of the same omen, lowers difficulty by 1.

Results:

• Success: Ask the Storyteller one question about the observed omen. More successes yield more specific information (“That man is your enemy” → “That man is your enemy because he hates your sire”).
• Failure: No information.
• Botch: Convincing false information.

This Merit applies only to Cainite affairs. It does not function for werewolf packs, mage cabals, or mortal conspiracies — unless those affairs intersect directly with Kindred politics.

Dhampirs

Thin-blooded vampires can sometimes conceive mortal children. This is not governed by a percentage roll — it occurs when dramatically appropriate and both Storyteller and player agree the development enhances the chronicle.

Dhampirs are born fully mortal, quieter and more prone to tantrums than normal children, but human. Their vampiric heritage manifests during puberty, when aging slows (but does not halt), they acquire Disciplines, and they become subject to the Beast.

A Dhampir is dangerous to have. The Camarilla declares them a Masquerade breach. The Sabbat treats them as Gehenna portents. Independent scholars and researchers regard them as rare specimens. The safest haven is with religiously inclined Kindred who view the conception as divine sign — though these protectors will have their own plans.

Dhampir Character Creation

Dhampir Special Rules

Blood pool: 10. Regenerates 1 blood point per day naturally. Can drink vitae to replenish faster, with all normal effects (blood bond risk, ghoul risk). All 10 points may be spent freely on healing, Disciplines, and Physical Attribute enhancement.

No nightly blood cost: A Dhampir does not spend blood to remain active. She is mortal in this respect.

Healing: Spends 1 blood point per bashing or lethal health level. Does not suffer aggravated damage from most sources. Soaks bashing and lethal damage with Stamina (as a mortal).

Regeneration: Can regenerate lost body parts with a successful Willpower roll (difficulty 8). Cost: 1 blood point per finger, 3 per limb. A failed roll cannot be reattempted; the body part is permanently lost.

Frenzy: Frenzy triggers at difficulty -2 (easier to enter frenzy than a normal vampire). Not subject to Rötschreck.

Disciplines: Disciplines cost 7 freebie points or 20 experience points per dot. May never be raised above 1 dot. Cannot learn additional Disciplines without an in-character teacher and Storyteller permission.

Sunlight: Does not suffer aggravated damage from sunlight.

Limitations: No Clan weakness. Cannot acquire vampire-specific Merits or Flaws. Cannot create blood bonds, ghouls, or childer. Cannot become a changeling, demon, mage, mummy, or werewolf. Can be blood bonded to a vampire but does not become a ghoul through this.

Imbued: A Dhampir can become Imbued (Hunter: The Reckoning) without losing the Dhampir template.

Mortality: The Dhampir is ultimately mortal. She ages (slowly). She can conceive mortal children.

Blood Rot

Blood Rot is a contagious disease that spreads through vitae. In mortals it presents as a severe flu (Stamina roll difficulty 6, or doctor’s attention, to shake). In Kindred, whose vitae is static and cannot renew itself, it is potentially lethal.

Contraction

Most vampires contract Blood Rot by feeding from an infected vessel. Deliberate transmission is possible through rituals such as Engaging the Vessel of Transference (V20 p.231).

Initial exposure roll: Stamina + Fortitude, difficulty 8.

• Success: Avoid infection.
• Failure: The vampire is infected.

Weekly Progression

An infected Kindred makes a Stamina + Fortitude roll at difficulty 7 each week.

• Failure: Lose 1 dot from a Physical Trait (player’s choice — Strength, Dexterity, or Stamina). This loss is permanent unless cured.
• Success: The disease does not progress this week but remains active.

Cure

• A level 4 Thaumaturgy adaptation of Purify Blood (V20 Rites of the Blood, p.147) targeting blood still inside the victim cures Blood Rot and reverses existing effects.
• Complete exsanguination of the infected vampire (draining all blood) also cures the disease — at the cost of near-certain torpor and Final Death risk for the victim.

Neither cure prevents future infection. Blood Rot can be recontracted.

Magical Variants

Certain blood magic practitioners (notably Sabbat infernalists) have created modified strains of Blood Rot that spontaneously recur even after apparent cure. A vampire afflicted with a modified strain must seek out the originating magical source to find permanent relief.
