Skills for an Inferno hero.

I largely agree with the above post. Logistics, attack, defense, and luck are always my priorities for this faction. The same applies to perks, but for luck, it's desirable to also take resistance, especially if you expect Darkness or Chaos from your opponent. I also don't like machines for Demons, even though ballistae have the highest damage for this faction. They are unreliable, especially knowing that machine operators are easily countered by one perk in Chaos. Besides, they are only useful at the beginning, and then luck will provide much more benefit. As for magic, I tend to favor Light. Mass Curse and Haste for a faction with high initiative and retaliation will be a big plus. Bless is also good, as Demons have the largest damage range, which is very useful. And Mass Stone Skin and Mass Dodge are also very good, as Demons often struggle against archers. But since Light is difficult to develop, the choice often falls on Darkness. I wouldn't be so categorical about Leadership. Morale can, of course, be obtained through artifacts, but the speed bonus for Demons is very useful, as the opponent may reduce their speed with Necromancer artifacts. Especially Archdemons lack it. Without a speed bonus, you have to stand in direct line of fire to take out archers. Tactics can also be countered if you're not playing as Nibros. But luck is still more useful. Sorcery is clearly not the way to go. However, the developers managed to give it to two heroes at the start, even Alastor, for whom it is completely useless. I don't understand this logic. At most, it can be taken for Chaos, but I rarely level up this school for Demons for one well-known reason. Education is still good for any faction in the late game, although the perks there are not very useful for Demons. So, in general: Logistics Attack Defense Luck Light or Darkness
