Walkthroughs for custom maps.

Where did you find such a battle? Can you provide a link? I'm talking about a 12-hour battle with turbo animation.

Here. Quote: "I also defeated the Moon with harpies on auto-battle; I had about 100 of them, and the battle lasted exactly 12 hours, including the time for creature animation with accelerated animation."

But this is an auto-battle, not a manual one, although unexpected crashes are quite possible.

I discovered that summoning pit lords is considered level 2 magic. You can't do this on regular terrain, but you can with a Cloak of Negation.

If this isn't in Physmig, you can write to the admin in the VK group (Physmig) to have it added.
