Your strategy for playing as Necropolis.

Inquisitor, I managed to get even more than 1500 in campaigns, even in version 1.5. For example, in the 3rd mission of the 3rd campaign, I didn't get any spells in the treasure room or pyramid at the beginning. And only a kamikaze would send a hero to fight Godric, who is already heavily upgraded, without a phoenix, berserker, or the Dominate skill. I had to wander around for several months.

And in the 5th mission of the 5th campaign, I got even more from six Necropolises. I had around 200 dragons there.
