A script I'm working on will be implementing this state effect pretty shortly. It wasn't planned to be in the next release update, but since it's been requested I shall bump it ahead.
I'll get to it now actually, since I have nothing much planned at the minute.
You can find this script here:
http://rmrk.net/index.php/topic,42238.0.htmlI will bump the thread and send you a PM when it's ready.
It also adds a lot of other states. They don't have to be used, but they aren't too bad to have. Also, this script is currently only designed for VX's Default Battle System. It probably won't work too well with any Custom Battle scripts without some extra work.
