The most effective starting strategy for the Inferno faction.

Yes, starting with demons is harder than with all the other factions. In reality, you can only start without losses with Deleb; it's easier with her than with the others, but I still think she's not the best hero among the demons (even though she's a machinist); Grog will definitely be better. On "Former Friends," when playing as demons, I usually upgrade imps and try to get as many as possible, even though they die in droves. They deal serious damage, and in the early levels, you can clear things out without significant losses once the first levels are cleared. Depending on the situation, we either improve the demons (against archers) or the cerberuses, but by that time, the problem isn't as acute. After all, opening the gate + magic, and the hero is also a bit leveled up. I usually build the guild on the second turn, although this again depends on the situation and the hero, but on "Former Friends," I build it on the second turn.
