With the EWa update, NCF is also being updated gradually. Will creatures from post 166 be added in the next patch? /attachments/47923/>
I will ask the author about this now. It is quite possible that he will add them soon.

• Added additional checkboxes for Eternal Essence when creating a network game. This allows you to enable or disable EE functions. It doesn't look very aesthetically pleasing, but there is no other way to fix the bug.
• The "Next Hero" button has been replaced with the "Sleep/Wake" button in the map navigation interface.
• The mana bar is now active by default and has a changed position on the hero icon.
• Some tooltips have been improved in the launcher.

The first two images are from the original game, the third image is with the modification.

Replaces the useless "Next Hero" button with the "Sleep/Wake" button
