Simulacrum
The duplicate is friendly to you and creatures you designate. It follows your spoken commands, and moves and acts on your turn in combat. It is a static creature and it does not learn, age, or grow, so it never increases in levels and cannot regain any spent spell slots.
When the simulacrum is damaged you can repair it in an alchemy lab using components worth 100 gold per hit point it regains. The simulacrum remains until it is reduced to 0 hit points, at which point it crumbles into snow and melts away immediately.
If you cast this spell again, any existing simulacrum you have created with this spell is instantly destroyed.
