Well, for starters, do note that you don't need to stop at 120 for stats or 25 for skills. I gave "Terra" an extra point of Body, for example.
Remember that you can make anything more expensive (or cheaper) with the wonderful variables in the "Customization" chapter. For example, right now, your illusions can be 10 meters big, but you can only make one, it only lasts a minute, and it's centered on you. You can add duration to make it longer (for 1 point an upgrade, illusion starts at Duration 3), be able to make them farther away with Range, or do more then one illusion at a time.
If you like, you can tell me what you want to do and I can walk you through how to do it.
