There are quite a few problems with your magic. For starters, there's a canon magic that is basically what your describing from what I gather. It's called [url=http://fairytail.wikia.com/wiki/Animal_Possession]Animal Possession[/url]. Secondly, even if you are trying to create a new magic it's far too vague. What are these spirits is he summoning? Where do they come from? How does he find and obtain these spirits? Why would they choose to lend him their power? Third, there's no consistency with the Spells you've described. They just seem to be abilities you specifically wanted. To the point where it one of them seems to be more of a detriment than useful. Why summon a weapon that does nothing aNY regular weapon couldn't but it drains your energy? The magic isn't very well thought out so I can'taccept this CS even if it were finished.
