Simple mod help

[Trumanator]

I am trying to make a very small simple mod that adds a holy booster and a new spell, but in my test game I can't get it to work. I am not yet sure about the booster, but I have a priest and when I open up his scripting options the spell isn't there. I also couldn't figure out how to add a completely new forgeable magic item, so I tried to have it replace the lightning rod, I'm not sure if I suceeded.
