The training rules for custom Kidou are as follows. Kidou levels one through forty-five require a training post of 500 words. Levels forty-six through sixty-nine require a training post of 800 words. Lastly, one of level seventy and above require a training post of 1200 words. This goes for each Custom Kidou, not the set as a whole. Make it believable, not a bunch of random stuff that has no bearing on Kidou training itself. I want a detailed, good training post with no lack of creativity. If it is horribly crappy, then expect a big old disapproval stamp from me.
