While I have a lot of goals I pursue in my various Monstrous Mondays, be it the creation of a new monster, adaptation of a monster from another source, or a review, my goal with the various Monster Manuals is to see if there is growth or even refinement of the monster entries.
This can easily be seen in the AD&D 1st Edition monster books as each, Monster Manual, Fiend Folio, and Monster Manual II, builds on the other adding refinements to the stat block. The same can be said for the 4th Edition books.
I would like to be able to say the same for the 3rd Edition books. Certainly, we saw improvements from MM1 to MM3, but those were largely due to the change in the rule system; that is 3 to 3.5.
I am particularly interested in these sorts of changes now that we are on the verge of One D&D from 5e. One sec, need to sip my Kool-Aid. Ok. Better now.
All is well and good, but what does that mean for the 3.5 Edition Monster Manual IV? Let us find out.
Monster Manual IV (3.5)
For this review, I am only going to consider the PDF from DriveThruRPG. I had owned this in hardcover largely due to the Blue Dragon on the cover (my oldest loves blue dragons) but it was auctioned off when I downsized my 3e collection.
PDF. 226 pages. Full-color cover and interior art.
This book does show some refinements and evolution. There are about 140 some odd monsters with a bit greater detail than previous ones. Often the monsters come with other details like a lair or use as characters.
Among the monsters here the ones I found most useful were the Avatars of Elemental Evil, the Balhannoth, some new demons, a few new drow types, some more lizard folk (I can't help it, I love those guys), some more orcs, the Spawns of Tiamat is rather fun too, and some new Tuan-ti.
There is not a lot of undead here, only 6 new monsters.
The biggest feature though is that all monsters are now on a "1 monster per page" layout, or span multiple whole pages like 2nd Ed and 4th Ed. This increases the value of the PDF in my mind and now I am not that sad I sold off my hard copy. Yes, today is the first time I have looked at this since then.
In many ways this book is superior to the Monster Manual III, layout just being one of them.
