Simulacrum

By means of this spell, the wizard is able to create a duplicate of any creature. The duplicate appears to be exactly the same as the original, but there are differences: the simulacrum has only 51% to (50% + 1d10% ) of the hit points of the real creature, there are personality differences, there are areas of knowledge that the duplicate does not have, and a detect magic spell will instantly reveal it as a simulacrum, as will a true seeing spell. At all times the simulacrum remains under the absolute command of the wizard who created it. No special telepathic link exists, so command must be exercised in some other manner. The spell creates the form of the creature, but it is only a zombie-like creation. A reincarnationspell must be used to give the duplicate a vital force, and a Limited Wish spell must be used to empower the duplicate with 40% to 65% (35% + 5 to 30%) of the knowledge and personality of the original. The level, if any, of the simulacrum is from 20% to 50% of that of the original creature.

The duplicate creature is formed from ice or snow. The spell is cast over the rough form and some piece of the creature to be duplicated must be placed inside the snow or ice.

The simulacrum has no ability to become more powerful; it cannot increase its level or abilities. If destroyed, it reverts to snow and melts into nothingness. Damage to the simulacrum can be repaired by a complex process requiring at least one day, 100 gp per hit point, and a fully equipped laboratory.
