Mordenkainen's Tome of Foes? Yeah, read it, talked about it. Here's an index of my read through:
The Blood War and Devils!
Drow and Eladrin!
Shadar-Kai and the Raven Queen!
Halflings and Gnomes!
But what about the Bestiary section? Look, it's full of monsters. It's got berbalang in it, but it doesn't have penanggalan. That's all I can tell you, really.
