Vampiric diseases come in many forms, Porphyric Hemophilia and Sanguinare Vampiris being the most common. Rarer strains of the vampiric disease include Chaotica Vampiris and Noxiphilic Sanguivoria.
No matter the origin, however, these diseases are related in one primary aspect in that they progress until the victim transforms entirely into a vampire. As they progress, they also share the same effects on their victims: starting with fatigue and a sensitivity to sunlight and progressing to a full-on sunlight aversion and an inability to satiate their hunger through normal means. As the transition into Vampirism progresses, the victim is often plagued by vivid dreams of consuming blood.
Shared Effects:
| Stage One | Stage Two | Stage Three |
|---|---|---|
| Weakness (Fire, 3) / Sun-Scarred (3) / Gain 1 level of Fatigue | Weakness (Fire, 4) / Sun-Scarred (5) / Gain 2 levels of Fatigue | Weakness (Fire, 6) / Sun-Scarred (10) / Eating does not satiate hunger |
Carriers: Vampires
Disease Progression: The effects of Stage One take hold after the character takes a long rest or at the next dawn; whichever comes first. After Stage One takes effect, the character must test Endurance -10 each dawn. If they fail, then the disease progresses to stage two.
Similarly, the character must test Endurance each dawn after Stage Two takes effect, but this time at a -20 penalty. On a failure, the disease progresses to Stage Three.
At Stage Three, the character must continue to test Endurance each dawn, but now at a -30 penalty. On a failure, the character dies painfully as their body succumbs to the illness. Then, after 1d4 days, they arise again, fully transformed into a vampire.
At any time during Stage Three, the afflicted active character can choose to succumb to the transformation by consuming the blood of any creature with a Black Soul (generally, sentient races) that does not have the undead or undying trait.
Once the character has completed their transformation, the effects of this disease are no longer active. After this point, the character’s vampirism cannot be cured by any commonly known mundane or magical means.
