How to write a good Dark/Light Magic System

[GunslingerRadiant]

I was making the outline of a story about two characters, that are the opposite of their respective magics. Now, their magic is very cliche (Spears of Darkness, Beams of Light). However, I want a more definable way to measure their strength. Any Ideas?

You could have the measurable bit be how many sol's worth of light is created(or destroyed) with most character only able to work with 1 sol but some people able to go up to 10ish sol's(the amount of light in the sun).

I enjoy that idea, however, the main character is the so called Herald of Light, and the only one that can use light magic. I give you my congratulations on a excellent Idea though.

is the same true for the dark mage?

Yes. He is the Lord of Darkness. They are both in their early teens.
