Here is the updated spreadsheet I made with all the monsters from the core book. Now, if someone knows how to make something automatically take the info from the monsters a user want and print something similar to what is in the core book, that would be really nice! (I don’t know how to do it; I don’t even know if that’s possible to do from a spreadsheet.)
It now contains the “kind-of-power-level” category that I was asking about in the first place (it did not seem to exist, so I did one). It’s not perfect, but I’m fairly happy with it.
