Blood
 
A rare element of dragon that needs constant bloodshed. When others are slain, they can absorb the blood on the battlefield through their scales to feed themselves which gains them more power. They can also do this by eating their prey whole. 

The least defence of all dragons due to their porous scales that helps absorb blood. Heavily hunted due to how dangerous they are. The more blood they lose, the hungrier they get. Their most popular prey are other dragons of other elements, especially their rival. Fighting is risky if this dragon isn’t on the winning side.
