Heart of Ice

This spell requires intense concentration (hence the long casting time) and can only be delivered by touch, requiring a successful attack roll to deliver on any but totally immobilized opponents. Victims turn black, are covered by a thin sheen of white frost, and instantly begin to shiver uncontrollably, making spellcasting, attacks, or any other activity except falling in a certain direction or shouting impossible. Victims must make a successful saving throw vs. death magic or die, as their hearts freeze and shatter. Those who successfully save suffer 5d8 points of internal damage instead, but as a side-effect are also rendered immune to all cold damage for 1 turn per level of the caster of the heart of ice. Creatures normally able to exist in frigid conditions (including priests of Auril, white dragons, remorhaz, winter wolves, and creatures from the Para-elemental Plane of Ice) are immune to this spell or suffer only 1d4+1 points damage from internal bruising.
