Upon meeting a Variabilis for the first time i was shocked to learn that their blood has acidic properties to it. How does it does not burn their body from within? Do they have a protective coating? or perhaps something they eat nullifies it? Either way the Variabilis have learned to use their blood for both protection and attacking. If they have to fight, many of them prefer to do and to hand combat as if they bleed their foes will become burned from the Variabilis slamming into them. Some take this a step farther and will use bloodletting techniques to store there blood in jars so they can coat weapons with them. They have even been known to sell their blood for quite a few sides, however the blood does not keep its acidic properties for long making finding a buyer quite difficult.
