Blood Puppet

The user chooses a single target within 60 ft. that they can see. The target must make a CON saving throw. If the target fails their save, they are then controlled. The user can make them do things such as attack, move (at half of the target's normal move speed), and some physical actions (at DM's discretion). The user cannot make the target speak or cast spells. At the target's turn, they can choose to make another CON save. If the save is successful, they are no longer under the effects of the spell, but cannot do anything until their next turn. 

For animals and monsters, they must be CR 5 or below. If the spell is cast at 5th level the CR can go up to 7. 

NOTE: The target MUST have blood. Otherwise, the spell instantly fails.
