I just finished a replay of FFIV, and actually took the time to steal DarkMatter from Zeromus. But, what I want to know is what it actually does. I noticed that his opening attack(s) involved Big Bang, Flare, and then another attack I've never seen called Wall which was very similar to Maelstrom. Does it do anything else aside from give him a new attack, or boost my stats, or what?
