Take out the manipulation part, and just make it a blood sensing Semblance. Semblances should be relatively simple and not too overpowered as that seems to be the case for most characters in RWBY (exceptions being the Schnees, Yang, and Pyrrha amongst a few others).

Limit the range according to the blood type of the source. Specify the exact distances in the General Limitations. Distances can vary, but nothing above thirty feet to keep it balanced.
 * O: 1 meters (3 feet)
 * A: 3 meters (10 feet)
 * B: 6 meters (20 feet)
 * AB: 9 meter (30 feet)​​​​​​
