All of these are excellent additions, that I would personally very much like to see implemented.

Though, as for resisting damage types, we actually can do that already. We can adjust the straight number of every element in the game, for any mob, even into the negatives. It makes for some pretty funny moments when mobs are set to -9999% weakness to certain elements.

I might have brain-farted and entirely forgotten that. W H O O P S. I'll edit my post and also add a new suggestion I forgot to mention.
