Karl Landsteiner’s Syringe

Origin
Karl Landsteiner was a biologist and physician who identified the main blood types through the kinds of coagulants in different bloods and how to safely perform a blood transfusion.

Effects
Allows for instantaneous blood transfusion when tapped on the arms, clearing the bloodstream of foreign agents and blockages. Will cause the blood cells to slowly degrade if used on people with differing blood types. The iron in red blood cells starts to decay and rust, leaking out any oxygen they were carrying. This cause an early release of oxygen, cutting off circulation and motor control to the digits, limbs, lungs, heart and brain. This can cause shortness in breath and rapid loss of consciousness.
