Blood Cauldron

 is one of the ultimate skills.

Skill Description
"Controlling blood is one thing. Modifying the blood cells is another..."

Some abilities are so powerful that even Vampires fear them. Blood Cauldron is one such ability. The vampire concentrates their power on one target and makes the victim's blood boil. Through this process, the vampire will regenerate, and absorb part of the target's blood. The vampire will release their prey after a few seconds, leaving damaging Blood cells within them. These cells will continue to impact their host, before exploding after a short time. The blast will affect any living creature near the host. Because of its dark nature, this type of ability cannot by used too often.

Tips
This was a very useful skill. Although it's damage was not as higher as Abyss, but it still worth to try, because it will have some blood absorb ability, which may help to recover your blood for other purpose. Just remember, when enemy is freeze, you can still damage them by using your weapon or other skills.
