Next, here are my thoughts and questions about the monster book from this boxed set.
I like the layout of this book, with roughly one creature per page. There are a few pages with two creatures each, and of course a bunch that take up more than one page.
Along those lines, I also like to see variant stat blocks for some of the creatures. For example, there is the vampirate, with mage and captain variants.
This book seems to fill in some of the setting lore that was missing from the Astral Adventurers Guide. For example, we learn (I think) that creatures can't reproduce in the Astral Sea, so they enter Wildspace systems to do so.
The book presents some ready-made plot elements, such as b'rohg gladiators, giff gladiators and githyanki laboratories.
What is the Far Realm? It is home to at least two of these monsters.
I really like starlight apparitions as a plot device.
A few of these present ready-made crews for vessels, such as negoi and vampirates.
All in all, I like this book. At 64 pages, it might be a little slim, but the content that's in it is solid.
