Hero replacer.

But the appealing version without armor seems to be lost in the annals of history((

In Heroes 5, they are absolutely identical, and in Heroes 6, they added a slight difference, probably so that players could distinguish them.
Vayre is red, with a weak flame.
Nebiros is orange, as if heated to the limit.

Well then, let Jezebeth be like that, since it's better).

And here’s the second part about Jezebeth… My disappointment is immeasurable, and my day is ruined.

Yep. But are there any differences from your Nebiros and Vayre from Heroes 5? I even opened the wiki for comparison, both the original and the modded versions, and I don't see any differences... It's not critical. I'm just trying to understand if there was any change at all.
