A message sent to me in spell cards

Question

My brother went missing a few days ago. No one has seen him since then. The day he went missing, I saw the following arrays of my new Dungeons and Dragons spell cards. I didn’t think much of it then, but now I think it’s a message to me. It might tell me where he is.

The arrays are, from top to bottom:

I also decided to add a picture of the card with all the class symbols on it, in case it becomes important.

Note:

1. The puzzle is contained entirely within the information on the cards. No D&D knowledge is required (though it may be minimally helpful.) Any required information is provided.

2. There is really only one main puzzle going on here. The rest is to point you towards it.

3. Most likely, you’re looking for the name of a place.

4. There is no information contained within the spell effect section (the biggest section of text)

That’s all for now. Good luck, and happy puzzling!

Hint 1:

Does a part of two of the arrays of faceup cards seem... similar?

Answer 1

Partial Answer

If you take the first letters of the each spell in the first set and interpret the upside down 7 as an L, you get LEVELS IN 4. Taking the levels of each spell in set 4 (assuming cantrips are 0) gives 240150180. Now using the A = 1, B = 2 etc. code, you get XOR, which is a kind of logic gate. I’m not sure how to use it here though.
