Vampiric Mist

By casting this spell, the priest brings into existence a malign, freezing mist in a hemispheric area with a radius up to 20 yards plus 2 yards per level of the priest. Within the mist, visibility is reduced to 10 yards and movement is reduced by 25%. Each round a creature spends within the mist, it loses 1d4 hit points from chill damage (no save, but magic such as resist cold halves damage) and must make a Constitution check or lose 1 point of Strength.
The fog travels at MV 9 over any and all terrain. It can follow simple instructions such as "pursue the dwarves on the hill, " but it does so with no real intelligence (if the pursued party splits up, the member(s) followed is randomly determined) and it has no special detection abilities (it cannot follow invisible creatures, for example).
For every 10 points of damage inflicted by the mist, the priest regains 1 hit point (normal maximum cannot be exceeded). For every 5 points of Strength drained, the priest regains 1 hit point in the same way.
For every creature slain by the mist, whether by cumulative hit point loss or Strength reduced to zero, the priest gains a surge of energy; this can be used to cast Cure Light Wounds on any creature touched, but this healing must be used within 3 rounds or the effect is lost. Any creature slain by the vampiric mist becomes a juju zombie under the control of the priest unless a save vs. death magic is successful.
The vampiric mist may be destroyed by a spell such as Gust of Wind, but it is allowed a saving throw vs. spell at the level of the priest casting the spell to avoid such destruction. It can be dispelled in the normal manner.
The mist cannot be struck with weapons or physically damaged with spells such as Lightning Bolt, although a suitable fire-based spell (Fireball, etc.) may dissipate and destroy the mist unless it makes a successful saving throw vs. spell at the level of the priest who created it. Normal fires do not affect the mist, nor do they prevent the chilling and damaging effect of the spell on creatures within the area of effect.
Finally, Strength points lost from exposure to a vampiric mist are regained at a rate of one per hour after escaping the mist.
