Blood Magic

A hooded man dressed in a scarlet red robe stands amongst a pile of corpses on the battle field, his hand glistening with blood. You watch as tendrils of crimson begin to flow from a near by fallen comrade and begin to turn into eerie strands as they circle him. He stares at you a crooked smile as the smell of iron fills the air. As you stand there frozen in fear the man begins to chant arcane incantation, a small dust storm begins to kick up around him but when the dust settles he's no where to be found. 

This subclass was created for use in the realm of Tylstaria, A world created by the DM of Twitch.tv/friday_night_dice.
