Which alternate upgrade for Inferno do you like the most?

I don't think it makes sense for a high-initiative race with the strongest attack potential in the game to waste turns on teleports... Just attack, attack, attack with everything and everyone at once, otherwise they'll overwhelm you in an instant (their defense tends towards zero). Here, you're thinking about whether to call in reinforcements or strike immediately... and they're using teleports...

And don't deny that teleporting a well-hidden enemy ranged stack will be very useful. It will be, I assure you. It's just that a demon, for example, can cast Confusion on these archers, and teleportation might not be necessary (you might even encounter a spell to dispel the Confusion). But that's just one case. And there's no need to complain about the defense. You can significantly strengthen the demons by upgrading their defense with the Stone Skin perk. ;) You might object, saying why would an attacking demon need defense? I'll answer: since we're talking about the improved level 7, it means we're talking about a relatively long game, and there might be a place for defense. But in general, I agree that attack is the element of demons. The old upgrade for devils actually embodies this element, but the new one turned out to be a little different.
