Vampiric Mist

The priest brings into existence a malign, freezing mist in a hemispheric area with a radius of 60 feet plus 2 yards / level of the caster.  Within the mist, the visibility is reduced to 30' and movement is reduced by 25%.  Each round spent in the mist causes 1d4 cold damage ( NO saving throw ) and must make a Constitution saving throw or lose 1pt of Strength.

The fog travels at a Movement of 9' and can follow simple instructions from the caster.

For every 10hp of damage inflicted and every 5 points of Strength taken, the cleric receives 1hp for each.  For every creature killed by the mist or reduced to 0 Strength, the cleric receives a bonus action.  If the fallen creature does not make its 3 death saving throws it becomes a " Juju Zombie " in the servitude of the priest.

Finally all Strength points lost from the mist returns to the character in one hour.  The duration of the mist is 1 turn + 2 rounds / level.
