Apparently,
nice announcements
are screenshots of the hero's skill tree. Well, that's not bad either.

No, these screenshots appeared even earlier; they were posted on Facebook on March 4th, if you look at the update date.

but I was somewhat surprised and disappointed that the hero's direct attack will now only be activated by a special ability.

So far, the talk was that the direct attack, which doesn't consume mana, would be left for all heroes without exception.

But I was pleased with the button that returns all spent skill points. A sort of field mentor, so to speak.

Most likely, this button only resets the newly spent skill points. If you close the skill window and open it again, it's unlikely that you'll be able to retrain the hero; otherwise, the imbalance would be terrible.

Given that there are now seven types of magic, this remains a strange mystery.

I think that not all heroes have access to all schools.
