Entropy is the name of the Trickster's last resort attack. If used on an opponent, chances of surviving are next to none. Only very few have the power or resources to avoid the attack.
How it kills
When the Trickster uses this attack he closes his and when he reopens his hand a small orb the size of a golf ball in his hand. Without a word the orb will fly out of his hand at the opponent that he wills it to. The orb flies at a quick pace but its not blindingly fast. The orb can be blocked by anything that isn't living. Once the opponent blocks the attack the orb splits into two orbs of the same same size and turns to attack the opponent again. If the opponent blocks those each one will split off into two and attack again. The more the opponent fights it the bigger the attack gets. Once one of the orb touches the skin of something living the object disintegrates where the orb hit it and the attack dispersal.
The name entropy comes from the the second law of thermodynamics which states that:
"The second law of thermodynamics states that in general the total entropy of any system will not decrease other than by increasing the entropy of some other system. Hence, in a system isolated from its environment, the entropy of that system will tend not to decrease."
Basically its stating that in a system, once an object has been moved, a sort of mixing and moving around of other objects has taken place that cannot be put back exactly where they were, or a continuing growth of chaos. Even if you try to fix one system, another system will be affected.
