Ugh. You’re gonna have me doing this for all the fields…
I see where this is going. 
Probably need more categories…
As BPIL, Happiness & Joy, and Intercession would be under “Minimal Energy”
Ascension, of course, is going to be “Max Energy”
and then “Low, Medium” “High”
which can and will change depending on people’s subsconscious resistance to the field.
And that’s all I’m writing for now lest I be pulled into a librarian category position where people want to argue how much one’s drained or not by each field and how “they can handle it”.
We saw how cranky people got about boosting…
But this is a good start.
