Concepts & Originality
Moodboard/Cover is cool and very spooky. The guy on the ghost horse with a flaming head especially
Flavor text could have been shortened and is a bit generic but works.
Rules Clarity
Many superfluous rules already covered by the Core rules.
Seem super complex. An npc model and a token mutation effect with five different mutations, multiple phases and bloodlust tokens and invocation tokens and you get tons of VP.

Would be better if you could pick up the token earlier than end of Turn 2. So the theme is there but it seems... difficult to get it to work?
