Army of One

"They say an army should act like one unit, what if they truly were" - Fendric a High Wizard Cloud Giant

You choose a creature within range and start a ritual that requires a long paragraph of runes and gestures for 5 rounds the caster concentrates on casting this spell and can move at half speed, finally at the 6th round they can choose any creature within their touching range and deal 25 health to them and take the blood from the creatures wound to draw a circle in the air with the ink pen, as your pocket gets light as the duplicates need compensation for their work.

Doing so creates 25 near exact duplicates of the creature that was the target of the spell. Each duplicate looks to be like the saturation on the target creature was decreased slightly.  Each duplicate has around 10% or 1/10 of the target creature's max hp (Rounded up). They have near Identical stats except for they are considered 5th level of one class the target creature is and can choose which class they are (all duplicates are the same class). 

The Major differences is that each duplicate is resistant all damage casted by a spell and they are immune to being Frightened, Charmed, and Exhausted conditions.
These duplicates are willing to serve under the target creature for as long as they live or as long as the spell last. As an action the target creature can use their action to command the duplicates to which they will do their best to complete and will adapt to their best ability. If the target creature doesn't take the action to command the duplicates they do as the target creature naturally would as they think, act, and know exactly what the target creature knows. 

The DM has full control on how the duplicates act and move, only guided by the commands the target creature give and who the target creature is needing to think like the target creature.

Once all the duplicates are either killed and or they fulfill their 7 day time frame the spell fades away. As the spell fades both the target and the caster of the spell gain 2 levels of exhaustion (if the caster targets themselves for this spell they gain 4 levels of exhaustion in total) and the caster must wait 1 week to be able to cast any spell above 3rd level. 

After this spell is casted it cannot be casted again for another full year.
