All of these mods are just begging to have some cross-compat here...

Please specify in details which parts are incompatible and what exactly should we do to resolve it?

It’s not incompatible, I was suggesting adding some cross-compat, such as allowing your content to deal more damage to things like demons, vampires, werewolves, etc, as a start

I would like to see this kind of compat with Haema mod as well. I also suggest to make it so holy spells using and wearing special armor will deal damage to lich players from Besmirchment, and to vampire players from Bewitchment and Haema
