ASW – Alternative hero leveling.

Chaos is basically only useful for elves for the enchantment and in the context of druids (if you give them Wasps and make the damage a little more significant, then Chaos is not so necessary). Without these 2 factors, it's useless to them. But Light + Summoning are suitable in themselves, based on the essence of the elven army. I won't explain why.

And just give it to them like that. Phantom has long needed to be available to all races.

It's even worse. Let's give resurrection to all races, because it's really needed. Why only the Necropolis can resurrect?

Will you reread what you wrote?

What's not clear? I would prefer an elf who has the spells he needs with the right summoning, rather than being given them for some unclear reason. As you said in Heroes 6? Casual gameplay?

And now it's an elf? Well, well...

And in a more detailed way? You just don't understand.

By the way, regarding summoning in the final version, why be stingy? With expert summoning, I can create copies of dragons, which, considering the initiative and high level of the hero, will definitely go at least once, i.e., they will already pay for themselves.

In your version with the free Phantom, you won't be able to summon dragons without the summoning skill. Unless you completely remove the Phantom's restrictions.
