Regarding dragons – there simply exists a rune of exorcism against sorrow. And the deadly gaze always works, immediately, and on everyone. The point is not about HP at all.)

It may exist, and it does exist, but he doesn't have it xD

He got an education to level up, but then he will cancel it with the mentor.
In general, the runes he got were: mage of watch/resurrection/dragon form/berserk/I think also elemental immunity...).

I'll see during the leveling process what the artifacts will be like. If in total he still has -5 defense, then I'll take an alt, and if not -5... Well, then I'll take ghosts.)

Regarding the hero, I agree that I was lucky. If I were playing as a gnome, I would only take Inga. Especially in the late game
