All u need to do is type amount of enchants and check coordinates of buttons/scrolls (it is based on resolution of screen, for instance if u have resolution 1024x768, middle point of screen will be 512,384 ; upper-left corner 1,1 etc.). Also very important is that while ACTool is running, l2 window must be activated! And u can't do nothing during executing script ;)
Just start script, activate ur l2 window and enjoy ^^
PS. if u have lags on server, increase delays (there are in ms, 1000ms=1second).
I hope it will be helpful :D
