you dont need any napbot for this.
btw, thing that i found out was:
when using any skills with 0 cooldown hack you must not click on the skill-button many times, just hold it for 1,5 seconds, then the skill will be done 2~3 times, then do it again. so your mana must not be used ^^ !!!! it works fine, just need to practice a bit. the thing is that the game reacts on the 'normal' cooldown and uses mana with 'normal' cooldowns when you hold the skill-button. just hold it for 1,5 seconds -> skill will be done 2 times and mana is used only for one skill use :D
