Simulacrum

Simulacrum is a highly potent spell that creates a surprisingly lifelike echo of its target. This echo remains under the control of the spell's caster until it is destroyed. Due to obvious impersonation reasons, the spell is illegal in most jurisdictions with regulations on magic.

Simulacrum

7-level Illusion

Casting Time 12 hours

Range Touch

Duration Until dispelled

Components V, S, M

Materials Ice, snow, straw, and/or mud in quantities sufficient to made a life-size copy of the duplicated creature; specially crafted crystal vial worth 500gp, and enough blood from the intended duplicated creature to fill it (consumed upon casting)

You shape an illusory duplicate of one beast or humanoid that is within range for the entire casting time of the spell. The duplicate is a creature, partially real and formed from ice and snow or straw and mud, and it can take actions and otherwise be affected as a normal creature. It appears to be the same as the original, but it has half the creature's hit point maximum and is formed without any equipment. Otherwise, the illusion uses all the statistics of the creature it duplicates.

The simulacrum is friendly to you and creatures you designate. It obeys your spoken commands, moving and acting in accordance with your wishes and acting on your turn in combat. The simulacrum lacks the ability to learn or become more powerful, so it never increases its level or other abilities, nor can it regain expended spell slots.

If the simulacrum is damaged, you can repair it in an alchemical laboratory, using rare herbs and minerals worth 100 gp per hit point it regains. The simulacrum lasts until it drops to 0 hit points, at which point it reverts to its components and falls apart instantly.

If you cast this spell again, any currently active duplicates you created with this spell are instantly destroyed.

Class(es): Wizard

Source

The magic of Simulacrum functions off the small amount of a creature's Soul that flows through their blood, magnified by the minute lenses of the specially-crafted crystal vial. This imbues the physical material of the simulacrum with a semi-functional illusion of the target, copying a snapshot of its abilities at the given time.
