Vee's simulcarum

You shape an illusory duplicate of one creature that is within range for the entire casting time of the spell. The duplicate is a creature, partially real and formed from Sand, slime or snow, 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 1/3 the creature's hit point maximum and is formed without any equipment. Otherwise, the illusion uses all the statistics of the creature it duplicates, except that it is a construct.

The simulacrum is friendly to you and knows you created it, but isn't required to obey your spoken commands, with a personality similar to that of the original creature . it can move and act in accordance with your wishes can act on your turn in combat. The simulacrum has the ability to learn or become more powerful, so it can increase its level and other abilities, and 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 10 gp per hit point it regains. The simulacrum lasts until it drops to 0 hit points or time runs out, at which point it slowly reverts to snow slime or sand, and takes 5 minutes to fully dissolve/melt away. during this time it can still act, however what it can do is dependent on what your dm allows it to do while it slowly melts/dissolves. if you use the spell on it again,  you can reform it and increase the spells duration. if kept alive for 5 days, it becomes permanent and. If you cast this spell again before the spell becomes permanent, any duplicate you created with this spell is dissolved in 1 minute. in order to create a new simulacrum after it becomes permanent, you must kill the previous one.
