In graphic design terms, the cleanest one I have reviewed, everything is colour coded, with different saturation so even printing in black and white things should be clear.
However...I can't say I love it. There's something about black and white.
Snappy, and to the point. I like that the Monsters have unique abilities and there's something more tactical here, though that may be due to the game this was designed for (I am not familiar with Lumendark...I am predominantly a solo game designer).
I ran out of gas, so my review is kept short.
