Pass it on
Blood aura could be used in several ways, and over the years, vampires have discovered many uses for it. Hardening the aura to use as armour over their bodies or using it as a pure form of energy to create temporary weapons.
The normal blood attacks can be used, such as the blood slash, which allows them to release the blood energy their bodies created. Some vampires could then use their blood control to move the blood aura or enhance it somehow.
However, the energy while out would dissipate as it hit objects or was in the air, and unless used to take a specific shape, it would just damage the other like a blast. What the others were witnessing was some of the most considerable amounts of blood aura they had seen.
