The blood nihil is a member of the nihil race, created by Zaros during his testing of genetic manipulation. By its examine, the blood nihil was likely created by weaving the essence of a vampyre. The blood nihil, like the other nihil in the arena, run across the halls and into holes in the wall, inflicting damage and a 100 damage Slaughter to any players that stand in its way. It always runs east, appearing from a different hole each time, until the player attacks it and draws its attention, at which point it solely focuses on using melee. The blood nihil has more health than its other counterparts.
