i think here it's the same like with metin2!
it WAS possible to reload the skills in a small period of time(normally takes 20seconds and with the hack only 1second)!
but it got patched same day(long time ago)!
it think at the beginning of shaiyaDE it was possible too!
if u have the oldest client and a workin bypasser maybe it works
but you have to find this single working hack
that would be the most difficult!
best regards
