I know I am late to the game. Just got back into DnD last fall and after being a player for 7 months I am taking over as DM.
That being said I just picked up the Tome of Beasts 5E. Overall I must say I love the book. I could use a few less CR20 plus threats, I know they look cool and are cool to read, but how many do you end up using really.
Well, I mean, you could use all of them even at low levels. 5E is deliberately designed so that monsters and PCs across a wide range of levels can interact. Just because your PCs are 3rd level doesn't mean a CR 22 Jotun Giant can't waltz right into their king's throne room, plop himself down on the throne (probably in shapechanged form), and declare himself the new king and the old king the new court jester. What are the PCs going to do about it?
I can think of at least one method which my players have in the past actually used which would allow them to depose and kill the usurper before the week is out. It might play out that way, or maybe they spend the next several adventures trying to rally enough common folk to their side to give them a chance to defeat the giant in open battle. Or maybe they try to toady up to it and become its favorites, and ask it for information on where to find good treasure. Or maybe they do something else entirely.
I'm just surprised at this idea that a monster in a book is useless to a DM unless the monster is something the PCs can kill in under eighteen seconds. It's not useless.
