"Note: Dice pool penalties from health level loss apply only to actions. They do not apply to purely reflexive dice pools, such as soak dice, most Virtue checks, or Willpower rolls to abort to another action. If a character is Wounded and suffers more nonaggravated damage, he may still soak with his full Stamina (+ Fortitude, if he has it). The health level penalties do apply to damage rolls for Strength-based attacks, but not for mechanical weapons like firearms. Ultimately, this rule must be adjudicated by the Storyteller and common sense. "

The wound chart with movement penalties will follow.
