| Core Mechanic | Roll d100 equal to or under your skill percentage. Success tiers at half (Hard) and one-fifth (Extreme) of the skill value. Bonus and penalty dice adjust the tens digit. Failed rolls can be pushed for a second attempt at greater risk. | Roll d10 minus d6 to determine which prompt to answer next — positive results move forward, negative results revisit earlier prompts. Each response creates an Experience assigned to one of five Memory slots (three Experiences per Memory). When Memory is full, old Memories must be forgotten or recorded in a Diary that can be lost or stolen. 72 prompts with three entries each ensure high replayability. |

| Best For | Investigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots. | Solo players who want a reflective, literary experience chronicling a vampire's centuries-long life as memories fade and relationships are lost. |
| Highlights | Sanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby. | Memory mechanic — five slots with three experiences each — reinforces the vampire theme of forgetting, solo with no GM needed, 72 multi-entry prompts mean different paths each playthrough, ENnie-nominated for Product of the Year and Best Rules |
| Considerations | Chase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaigns | Pacing is entirely self-directed which can lead to uneven sessions, memory management rules can feel arbitrary when forced to forget key experiences, prompt entries can become repetitive in longer playthroughs, no external structure to signal when the story should end |
