By the way, you could take the vampire from the seventh game; it has teleport instead of movement. It should work smoothly, even if the effect is from the fifth game. Just an idea. And in general, you could create a bunch of units with teleport. Teleport the abbot, the lich, the vampire, the djinn, the mage on a carpet, etc. Just an idea.

Thanks for the answer about the Justiciar :) the option like the existing guys is exactly what's needed.

Yeah, Chaos Theory promised to add demons, showed videos, fed us with screenshots, and then poof, nothing.

This mod is still active, by the way.
