Fast Healing (Ex): A vampire heals 5 points of damage each round so long as it has at least 1 hit point. If reduced to 0 hit points in combat, it automatically assumes gaseous form and attempts to escape. It must reach its coffin home within 2 hours or be utterly destroyed. (It can travel up to nine miles in 2 hours.) Any additional damage dealt to a vampire forced into gaseous form has no effect. Once at rest in its coffin, a vampire is helpless. It regains 1 hit point after 1 hour, then is no longer helpless and resumes healing at the rate of 5 hit points per round.
