Depending on Damage, if you are past Incapacitated, you are automatically in Torpor or
may suffer Final Death.
Exceptions - Dice pool penalties from health level loss apply only to actions. They do not apply to reflexive dice pools such as soak dice, Virtue checks, or Willpower rolls. The health level penalties do apply to damage rolls for Strength-based attacks, but not for mechanical weapons like firearms.
Power of Will
The will of a person can be quite strong and never underestimated, this is doubly so with a Vampire. Because there are many ways to use Willpower it is important to know how it works.
A player may spend one Willpower point to gain an automatic success on a single action. Only one point of Willpower may be used in a single turn in this manner, but the success is guaranteed and may not be canceled, even by botches. By using willpower this way it is possible to succeed at a given action simply by concentrating. You must say you are spending Willpower before you roll
A player may spend a Willpower point to prevent a derangement from manifesting, with the Storytellerís permission. Eventually, if enough willpower points are spent (as determined by a ST), the derangement may be overcome and eliminated, as enough denial of the derangement remedies the aberration. This of course may not be used to overcome the Malkabianís initial derangement, though Willpower may be spent to deny it for a short period of time.
A player may spend a Willpower point, wound penalties can be ignored for on turn. However, an incapacitated or torpid character may not spend Willpower in this manner.
When in the throws of frenzy you may spend a Willpower point. This enables the vampire to control themselves to make one action for one turn.
