Appearance/discussion of Inferno units.

Inferno isn't very good. Especially the demons with the flames of hell and the withering flame, and I think Pit Lord is the most powerful mage in the game because of his meteors. By the way, if you destroy the main stack of reinforcements, they will still reappear, and if you upgrade the Main Gate of Hell and get very lucky, you won't be able to destroy the reinforcements.
