NCF – Extended list of Neutral creatures.

These creatures are not from Heroes 7, but from 3.58. Of course, they won't be as strong there as they will be here. + Perhaps, for those to whom I assigned the charge attack, we should remove the flight ability, just in case it doesn't work 100%. And all of them are large creatures.

And there are 8th-level creatures there, besides dragons; these are just recolored versions. They look exactly like 7th-level creatures, but with a different color. Many of them already have immunity to deadly cold, but the cave demon's blade, spirit ability, or crossbowman's shot or charge attack MUST take them down; otherwise, it will be impossible – crystal scales will definitely be unnecessary, and the originals don't have immunity to damage reduction either – I tried to make the abilities as close to the original as possible.

And in general, there are also some divine creatures and 2 words and summoning spells that can defeat them.

They should be made in a similar way to the Mystdragon (just recolored the astral dragon), and that's it. An example is in the attachment, as someone has already done.
