Appearance/discussion of Academy units.

If you think about it, nightstands are present in many games. Well, maybe not many. But they are in Warcraft! The Obsidian Statue, I think. However, there it was more of a support unit and never attacked, but it could transform into a Sphinx (another nightstand, but one that loots and throws things). :(

Actually, I've seen footage where they attack with statues... But when they transform, they become a practically invaluable unit for the Necropolis army.
And if we go back to our nightstand, its stats are shocking... With such stats, it only takes a week of growth to clear the entire map. The set of immunities is impressive:)
