Need Free Auto Curser

hi guys and gals, i need a free auto curser that simply clicks on the curse spell and then clicks at the monster... also if you are feeling even more generous could you make it run if it starts getting attacked and then make it run back and start cursing?

ps i have had a go at coding one myself but its dismal and keeps getting runtime errors etc.... if anyone could code this for me it would be a GREAT help
