effect name cannot be traced by looking at it lol the name depands on the creators creativity. But it depends on what item that gives this effect.
If its a casual its not that hard to trace.

I bet this effect already in the client side but i dont know what are the folder name...
Hmm...i think SoulNecturn know this heh
