Mage skill hack problem

I managed to do the skill hack on mage in elitedekaron whit winhex. Skills that i made is imitid flash and gracious eddy.
My problem is: The monsters(ex.a boss in Hell on Earth) dont die with 1 skill, i need 4-5 minutes to kill the monsters and i used +5 times the skill. How can i do to kill the mobs whit 1 skill in 30- sec. Or tell me another skill hack.
Thx.

???

If I remember well, (I don't know if it's still working) to make skill hack in elitedekaron I had to unpack data with packmanager etc etc then pack it up again (I guess everyone knows that). I couldn't kill the bosses in 30 seconds either though.
