Beneath the Borderlands
The caster creates a duplicate of himself or some other person. The basic form is created from snow and ice, and must then be animated (Animate Dead is an acceptable means). A Limited Wish (along with the actual simulacrum spell) is then used to imbue the animated form with intelligence and certain knowledge of the person being simulated. The simulacrum gains 30–60% (use a d3) of the simulated creature’s knowledge and experience. The simulacrum follows its creator’s orders. It is worthy of note that the simulacrum is not a perfect representation of the original. Side by side, the differences are obvious, and the simulacrum is a magical creature detectable with a detect magic spell. If the original of the simulacrum dies, a strange effect begins: the simulacrum begins to gain the knowledge and experience of the dead individual at a rate of 1% per week (to a maximum of 90%).
