Within each generation of vampire, the strength and potential of what their Blood can do varies. The longer a vampire survives, the more potent their Blood can become. Increased potency comes with greater risks. The effects of a vampire’s Blood Potency are summarized below:
Blood Potency 0 (zero):
You are a thin-blood, not quite a vampire and no longer truly mortal.
● You may Rouse your Blood to increase your pool by +1 for a single challenge that involves any of your Attribute scores.
● You take damage as if you were a mortal unless you possess the Thin-Blood Merit: Vampiric Resilience.
● You may Rouse your Blood once a turn to mend one point of Normal Damage if you possess the Thin-Blood Merit: Vampiric Resilience.
● You have no Bane Severity because you have no clan and therefore no clan Bane. ● You cannot create Blood Bonds or create ghouls without the Thin-Blood Merit: Catenating Blood.
● You cannot Embrace vampires without the Thin-Blood Merit: Catenating Blood. ● You are susceptible to a Hunger Frenzy the same as true vampires.
● You are only subject to Fear and Rage Frenzy if triggered by a supernatural effect such as Animalism unless you possess the Thin-Blood Flaw: Bestial Temper.
● You take only one point of Normal Damage per turn in direct sunlight. Blood Potency 1
You are a true vampire. Even at this lowest level of Blood Potency, you can accomplish great things.
● You may Rouse your Blood to increase your pool by +1 for a single challenge that involves any of your Attribute scores.
● You may Rouse your Blood to mend one point of normal damage.
● You have a Bane Severity of one.
● You can create Blood Bonds and ghouls.
● Once per night, when not in combat, you may ignore one failed Rouse check to employ level 1 Discipline powers.
● You can Embrace other vampires.
● You are susceptible to all forms of Frenzy (see below).
● You are susceptible to all the Prices and Dangers of the Blood (see below). Blood Potency 2
The strength of your Blood grows; however, blood not fresh from a human begins to lose its sustenance. You gain the all the effects of Blood Potency 1 with the following modifications:
● When you Rouse your Blood to mend damage, you mend two points of normal damage (instead of one).
● When feeding from animals, you may only Slake on large animals and, when doing so, only Slake one Hunger (instead of two).
Blood Potency 3
Your Blood has thickened enough to render you no trivial threat to others; however, it also causes further limitations. You gain the effects of Blood Potency 2 with the following modifications:
● When Rousing your Blood to increase your Attributes, you gain +2 (instead of +1) for a single challenge.
● You may no longer Slake Hunger from bagged blood or animals.
● Once per night, when not in combat, you may ignore one failed Rouse check to employ level 1 or 2 Discipline powers (instead of only level 1 Discipline powers).
● You have a Bane Severity of 2.
Blood Potency 4
The strength of your Blood exists below that of the most powerful vampires but allows you to exercise your will over most of the rest of your kind. You gain the effects of Blood Potency 3 with the following modifications:
● When you Rouse your Blood to mend damage you mend three points of normal damage (instead of two).
● You may no longer Slake Hunger by Sipping from a human. When you Slake Hunger with a Non-Harmful drink, you Slake one less Hunger.
● You gain a +1 bonus to your defensive pools when defending against a challenge caused by a Discipline.
Blood Potency 5
The strength of your Blood approaches that of elder vampires. Should it increase further, you will surely fall to the Beckoning. You gain the effects of Blood Potency 4 with the following modifications:
● When Rousing your Blood to increase your Attributes, you gain +3 (instead of +2) for a single challenge.
● Once per night, when not in combat, you may ignore one failed Rouse check to employ level 1, 2, or 3 Discipline powers (instead of only level 1 and 2 Discipline powers). ● You have a Bane Severity of 3.
● You must drain and kill a mortal to reduce your Hunger below two.
Blood Potency 6 and Higher
Vampires of this Blood Potency are disappearing from the world. Those who remain struggle to resist the Beckoning. Player characters can only reach this level of Blood Potency temporarily through certain supernatural powers such as Animalism and Blood Sorcery. Those powers will detail the effects of such an increase in Blood Potency.
