Simulacrum

Simulacrum
7th-level illusion

Casting Time: 12 hours
Range: Touch
Components: V, S, M (snow or ice in sufficient quantity to make a duplicate of the creature to be copied; some hair, fingernail clippings, or other piece of that creature's body placed inside the snow or ice; and powdered ruby worth 1,500 gp, which the spell consumes)
Duration: Until dispelled

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

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

If the simulacrum takes damage, you can repair it in an alchemical laboratory, using rare herbs and minerals worth 100 gp for each hit point it regains. The simulacrum lasts until it drops to 0 hit points, at which point it reverts to snow and melts away instantly.

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