Demon invasion.

Completed 1 mission of the updated campaign. It’s tough as always. I don’t know if it’s intentional or just the author’s design, but I was lucky that in a few battles, around 380 skeletons and 150 zombies joined me. These undead (a pack of archers + zombie level 2 units) helped a lot in defeating packs of druids and titans, which can’t be countered with gates or dispel. I played with darkness + summon (must-have: wall of swords, which I found in a temple purely by chance, and also phantom). From the Light faction, I only had regeneration, which means if you play with your native army, you can’t regenerate your troops. There was no berserk or enthrall. It’s noticeable that the initiative is boosted even for neutral creatures (I had a staff + ring of swiftness), but even under slow and with skillful use of darkness, they didn’t slow down much.
