Shadow Simulacrum

Description
Shadow Simulacrum reaches into the Plane of Shadow and creates a shadow duplicate of the creature touched by the caster. This shadow creature retains all the abilities of the original, but is created with only 3/4th the current hit points of the original and all memorized spells are lost. The simulacrum has 20% concealment and immunity to negative energy damage. Creatures with more than double the caster's level in hit dice are immune to this spell.
