Does mob PDDamage still work?

True, but why did nexon give the monsters these variables then? If they were never going to use it, why did they bother to add it?

It's not that they added them recently for no reason, it's more like they didn't take them out, like they do with a lot of things they don't use anymore. I don't know the technical term, but I guess I'd call it an vestige of the old system
