There are some monsters that have plurals here and others that are singular (ropers and remorhazes, right next to revenant). Are you indicating that there are multiple types of these, or is this a typo?
Only three gemstone dragons and three essence dragons? No more crystal, blight, celestial, chaos, sea, spirit, or underworld dragonborn?
Why do grimlocks get a Legends and Lore section in the ToC when no other creature has that? Is this a typo?
No wererats? <snif>
I'm guessing "malcubus" is the term for incubi/succubi. And I'm kind of surprised that scarecrows aren't a type of guardian.
Fomorians are a type of titan now? Interesting! Are they "fallen" titans? Or something else?
Can I hope that horde demons are a version of hordelings? I miss those guys.
I'm assuming that invisible stalkers are elementals in the vein of azer and xorn. So why no water weird?
Also... adamantacore? boooo.
