This is one of my versions of the advanced PSI ball
It is used as an offense spell it can also be used as a defensive spell if you know no haw to. I would suggest using this to defend yourself only. it is used to deal massive damage to a physical object like breaking bones or busting organs
there are two ways that you can learn this technique I will give you the first one and most likely the easiest
create a PSI ball push energy into making it the expand the careful how much you put into it though if you start filling fatigue to stop and rest when you have not done expanding it collapsed the ball in on itself compacting the energy into a even tighter and tighter ball once you do this for several days straight you should be able to use very little energy to do this you will know when you are done when you are able to break a physical object or damage it in any way with this technique
I forgot to add that the PSI ball that you have created should not be stored or attempted to store it if you do you risk your life in the ball will continuously draw energy from you until you have no energy left for it to take. win this point is reach your body cannot support itself and will fail in Lehman turms you will die
You will need a lit cigarette a glass of water a rock and you will not need anything to represent air for the fact that it is all around you have someone switch all of these objects around that way you do not know which is which have your eyes closed and clear your mind out everything now and feel for a poll to the element that is yours picked the object up and open your eyes if you do not feel a poll to any of the objects thin your element is air
you may use insints to replace the cigarette
Nine out of 10 of all my spells are aura based so they use your life force it is more dangerous I would have to say but it makes the spells more reliable
