Currently I've seen that it's only possible to set in general to give them Armor in generally.
I think it'd be nice if we'd be able to set for every mob possible Armor they could get depending on their Difficulty.

Example:
modid:name; difficulty; armor_piece; unlocalized_name; weight
minecraft:zombie; 250; chest; minecraft:diamond_chestplate; 100

I'll consider it. That would probably be a major rewrite of how blights are given armor.

Yeah I thought so ^^ '
And also I didnt only mean blights with that, basically why I am requesting this is to balance everything a bit better. Looking through all the Mods I founded there is basically none able to balance everything. You'd have to decide Harder Early or Late Game, and since Scaling Health has already a bunch of balance features for mobs, this'd be thing to increase balance even more.

Btw while looking through the configs I noticed it is only possible to set additional health for non-blighted mobs, is intended/should I regen the config or is it just missing?

OK, I'll see what I can do. Not making any promises, but I do think that would be a nice addition.

Currently, blights have a fixed 3x multiplier on difficulty, so they should gain around 3x health. I plan to add a config for that.
