Skills for an Inferno hero.

Again, I repeat, there is NO NEED to upgrade Chaos skills beyond the basic level. The core spells will be Ice Bolt and Ring of Fire. The difference between an expert in Chaos and the basic level is only 24 damage in these spells. So, we take the basic Chaos skills – Lord of Cold. The basic level is also sufficient for learning Cold Steel. If, instead of ice spells, fire spells are available, then we take the basic Chaos skills – Lord of Fire. Nothing else is required. In my opinion, Magic Depletion is not useful for demons, as it requires level 4. It is easier to take basic defense skills – Reflection, if you need to protect yourself from magic (and it is even better to take a Marbas hero right away, as he is anti-magic and already has Reflection) + defense has many other very useful skills, and defense itself is a mega skill for demons and not only. Advanced Chaos makes sense to upgrade only if you are afraid of enemy machines (Deadly Cold) or if you are playing as Groll (he already has advanced Chaos).
