This potent herbal blend induces slumber almost immediately. The target must roll Stamina (difficulty 8) or spend a point of Willpower to stay conscious; he must remake this attempt (at a -1 to Difficulty each time) every round until he succumbs or the drug no longer has a chance of success. Unconsciousness lasts for (10 - Stamina) hours, during which they cannot be roused. Vampires are almost immune to this drug (+2 to Stamina, add Fortitude and effects, if they succumb, last 10 - (Stamina + Fortitude) minutes), but werewolves in their “normal” form (Homid or Lupus) are susceptible (+2 to the roll).
