When the caster drops to 0V outside its resting place, the caster transforms into a cloud of mist instead of becoming Dead, provided that it isn't in sunlight or running water. If it can't transform, it is destroyed.

While it has 0V in mist form, it can't revert to its vampire form, and it must reach its resting place within 2 hours or be destroyed.

Once in its resting place, it reverts to its vampire form. It is then Paralyzed until it regains at least 1V.

After spending 1 hour in its resting place with 0V, it regains 1V.
