Blessed Resilience
This power was presented as a Fortitude 8, Mortis 4 discipline technique. However, the DA2 rules indicate that powers of above level 5 do not need accompanying disciplines. Also, Mortis is not a discipline, but a path and style of Necromancy.
Millennia of passivity in the face of opposition breeds an indomitable constitution. Vampires with this power have been known to rise from Final Death. Limbs and Appendages reattach themselves if severed, and heads reknit themselves to necks, if need be. Anyone attempting to exterminate a Cappadocian had better be sure that her "victim" does not command this power or she may find herself with a powerful, very long term enemy.
System: In the unlikely event that the vampire using this power has any Blood Points left, she must spend them all. In addition, four Willpower points must be spent, plus one if the head must be re-attached. If the Cainite does not have enough Willpower, she experiences Final Death as normal. Severed limbs will crawl back to the body (an unsettling sight), and the vampire is miraculously healed up to the "Mauled" Health Level, and hopefully crawls into some hole where she can recover further, given time. The vampire enacting Blessed Resilience permanently loses one dot in every Attribute. These dots are "crossed off," and may never be recovered. This will result in lower maximum Trait ratings. This power, when necessary, takes effect automatically and immediately, and the would-be killer may freely interfere with it (if she is smart enough to see the job done). Note that catastrophic damage, such as diving into a live volcano or being deposited in a field at noon, is still fatal, and beyond the regenerative capacity of this power.
