The Tunnels & Trolls 7.5e Monsters & Magic Book (Special Edition) is a 22 page booklet included in both the T&T 7.5e Boxed Set and the 30th Anniversary Tin. As far as I can tell, this booklet introduced Special Damage to the T&T game (I don't see it in my 5e copy of the rules, and I'd need to dig to find my 5.5e copy).
previous post about the Monstrum Codex.
We also get a few paragraphs on Balancing Encounters in T&T 7e/7.5e, which is based on a 4 character party. Strangely enough, the Balancing Rules that make mention of the Revised T&T rules (presented in the 30th Anniversary Tin and available for free at Trollhalla for registered members) refers to a Standard 3 person party. I might need to give the Revised (think alternate) T&T rules a closer look.
In any case, the booklet details 20 creatures for use in your T&T game.
The rest of the booklet gives a short and dirty introduction to magic items in T&T. It's enough to give the GM some ideas, but little more. Sample staves, wands, potions and weapons are stated out. It's a start, but leaves me hungry for more.
All in all, there's a lot of info crammed into those 22 pages. How about we get a book 2? ;)
