Wrath of the Kaza

I think that was the original idea for blade master DFO Gold, but they took the character in another direction. GSD specifically mentioned it during the class quest back in Nexon days.   I'd like to see some more flashy striker moves and more combo type attacks, like an attack that hits 3 times or something like tiger fist, with say a front roundhouse, back roundhouse to butterfly twist.

Wrath of the Kazan - 2 Clear Cubes - Buff - 5 min CD.
Whenever an enemy is damaged by a blood skill, their blood becomes diseased, turning them into a walking plague. For each enemy they get close to, it will spread to each of them and inflict a fixed amount of damage per second for 10 seconds with an increased chance of bleeding status, decreasing their bleeding resistance. The more enemies gathered...the longer the disease persists.
