A wretched entity of the frozen lands, the WinterKill is the remnant of a mortal left to die in despair and endless cold.
There are many dangers at the poles and in the icy mountians of the world, but few dangers are harder to survive then an attack from an Ice Ghoul, a shadow-spirit whose very touch can be deadly.
A certain type of demon cannot not be hit by ranged weapons or attacks. Attacks have to be made up close and personal for the damage to mean something. Ranged attacks are to impersonal.
Possibally a way to make the ranged attacks more meaningful would be to coat the arrow head or what not with the shooters blood. Of course, they'd better be a good shot, otherwise they're wasting arrows and already bleeding to boot.
Spells: wizards might have half or no effect, preist might work due to divine intention.
