The Troll's Companion

from the Introduction:
Welcome to the Troll’s Companion, a sourcebook written entirely for the modern-day Tunnels & Trolls gamer.
...
This companion is written to work well with what ever edition of T&T you prefer. The main purpose of this book as I see it is to get all of my little rules and variants out for T&T and under one cover, where anyone who enjoys the game can browse and sample to taste. Within the Troll’s Companion I am offering up hundreds of magic items, monsters, class options, combat options and new spells. Nothing in here rewrites or changes the core rules in any way; it’s all supplemental information, stuff you can tack on, plug in, and have fun with. Want some variant class ideas? Add a few archetypes. Need some quick magic items? Pick a chart and roll or choose. Want some combat maneuvers to spice things up? Pick your favorite and go for it. Need some new spells or monsters, or the old brain need a kick-start for inspiration? You’ll find it all right here.
