Demon invasion.

I specifically registered to leave a comment. In general, I played until the point where they took everything away, and it became uninteresting. Regarding the hardcore mode, the way to progress is to max out defense with Battle to the Last and Leadership with Devour, then I easily defeated everyone in packs of 4 Imps. For Colossi, I surrounded them with summoned Imps, so only one of them attacks, and the other two defend, and then I attacked with magic. It turns out that the Thunderclap spell needs to be cast ten times to defeat real Imps. And in the same way, it's easy to defeat Angels, and generally almost everyone.
