Blood-Bound Golem (Humanoid Form)

Blood Bound. This golem is bound to its creator by a single drop of the creator's blood. It will only take commands given to it by its creator. The golem deactivates permanently if the creature it is bound to dies. The creator can willing give away control of the golem by drawing blood from another creature and dripping it in the golem's mouth. 

The creature can only be blood bound to a maximum of 5 blood bound golems at one time, if the creature binds to another blood-bound golem the oldest golem deactivates permanently and the creature takes 3d6 necrotic damage.

The Golem only obeys the blood bound creature's commands to the best of its ability but cannot attack. 

Immutable Form. The golem is immune to any spell or effect that would alter its form.

Alert. The golem uses its action to detect life in a 20 foot radius centered on itself. 

Full cover does not hide a creature from detection, unless that creature is behind 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.

If the golem detects a creature that it is not familiar with, for the rest of its turn, it will look directly in the creature's location and shed a beam of bright light on it. If the creature moves the golem will track it with its light. If it detects multiple creatures its head will spin in a circle shedding a beam of bright light as it spins.

This ability does not work on undead, constructs, or  creatures using magical means to  hide their life, like the spell Feign Death.

Suppress Magic. When one creature within 10 feet of the golem is hit with a magical attack the golem can use its reaction to reduce the damage by 1d6.
