click and hold A S D F (if you have all arrow attacks) and click outside the game screen. you can use that glitch on "mana growth" too, just click and hold "r" and click outside. If you going somewhere in real life, you can leave it, when you come you will see you got 9999 mana, it will be easier to end mission, and you will get alot of experience, BUT you must select mission what have monsters enough weak to don`t pass through the line of fire
