Wanted to elaborate that Darkness can absorb negative energy even if they are attacks or lesser beings made of negativity. Although it was obvious since he feeds of negativity just wanted to clarify.

And a question. Are curses, dark magic, death magic made of negativity? I know that curses are fueled by them so if Darkness absorbs someone's negativity while they are casting a curse, it becomes null?

Sorry if this seems like a new ability/skill but I didn't seem to have elaborated enough on it.
