The ability to
create tools, objects, weapons, armor, and even appendages out of blood. Sub-power of Blood Manipulation. Variation of Anatomy Constructs and Liquid Constructs.
Users can turn blood into tools, objects, weapons and other items, create semi-living constructs and/or create structures/buildings of varying permanence. Users who have mastered this ability can use it for almost any situation, creating anything they need.
User can create any item they have seen or can imagine and have a good idea how it functions. Short list of possibilities includes:
May be unable to create blood, being limited to shaping from an already existing source
Using too much blood may be lethal.
Construct structural strength may be limited by the users will.
In most cases constructs will return back into their original state if the User becomes unconscious, leaves the proximity or otherwise loses contact/control of the item.
May be limited on how complicated constructs they can create (ie. no/limited amount of moving parts).
