Like many authors here, I plan on using magical elements in my story. However, Unlike the typical wands and wizards magic, I want to make it a form of measurable, quantifiable energy. Characters will have X amount of magic, which is measured in terms of "sparks". Magical energy basically works like alchemy a la Fullmetal Alchemist, except there's no need to draw circles first. Long story short, I need help reigning in this strange power. I need to set boundaries for it, but since I'm terrible at physics, I need some help.
