This seems really interesting and useful. I have suggestions though:
1 - Ahhrgg remove the little letters or make them bigger! It's a pain to me (the reader) because I am actually interested in learning as much as possible from this tutorial and you just make my job harder.
2 - You definitely should add more images. Btw, I couldn't tell but, is the image attached to the post?
3 - You should really make an "example map" available for people to see it's use in action.
There are some things I didn0t understand like, can I use this dynamic thing and order it to look for the damage my JESP spells make, by pointing it out the function and the trigger?
So, what if this is a dummy ability and everything is coded? This will be useless right?
Keep on the good work dude!
