[Spells help] voodoo

Syntax: cast voodoo 

By calling upon the power of voodoo, a shaman convinces his ancestor
spirits to summon the ancient voodoo spirits. Once summoned, the voodoo
spirits will seek out any one person in the realm and cause their body to
contort with unbearable agony.  If a spirit doll of the target is in
the possession of the shaman, the spirits will not have to waste energy
searching and will do much more damage.  Contact with the voodoo spirits 
will frighten all other spirits away from the shaman for a time, rendering 
him powerless.  Voodoo spirits do spiritual damage and as such the spirit
aura of another shaman can completely shield the victim from harm.
