Blood Points (The Core Resource) A Vampire's supernatural abilities are not infinite. They are fueled by Blood Points, a resource that represents the stolen life force of living creatures stored within the vampire's optimized cellular structure.
Fueling Immortality: The GM must track this resource carefully. Blood Points are expended to fuel supernatural regeneration, flesh-freezing techniques, pressurized optical lasers, and grotesque physical mutations.
Resource Management: Narratively, without this vital fluid, a vampire's cells will stagnate, temporarily stripping away their immortality. Mechanically, a player regains their entire pool of Blood Points upon completing a long rest. However, to survive prolonged engagements, this resource must be actively maintained on the battlefield.
Active Maintenance: The Blood Drain At Level 2, Vampires gain the "Blood Drain" feature, which is the primary method of sustaining their immortal flesh mid-combat. The GM must understand the specific action economy and tactical risk of this ability:
The Prerequisites: A vampire cannot simply drain a target running past them. To initiate a Blood Drain, the target must already be grappled, incapacitated, or restrained.
The Cost and Attack: The vampire uses an Action and spends 1 Blood Point to make a special unarmed strike against the target.
The Healing Effect: On a hit, the vampire sinks their fingers directly into the victim to drain their vital fluids. The attack deals 1d6 necrotic damage, and the vampire instantly regains hit points equal to the necrotic damage dealt.
The Lethal Payout: The true purpose of Blood Drain is resource recovery. If this specific attack reduces a living humanoid to 0 hit points, the vampire does not just heal—they instead regain 1d4 Blood Points, violently replenishing their internal reserves.
