Re: Game On!
I happen to have a slim, basic, basic, D&D rule book for both DMs and players. It lists these monsters:
Basilisk Bat (normal, Giant) Bear (Black, Grizzly, Polar, Cave)
Beetle, Giant (Fire, Oil, Tiger) Black Pudding Bugbear Carrion Crawler
Cat, Great (Mountain Lion, Panther, Lion, Tiger, Saber-Tooth Tiger)
Centipede, Giant Chimera Cockatrice Crocodile (N, L, G)
Cyclops Displacer Beast Doppelganger Dragon (Colors, no size discrimination)
Elementals (Types, no size discrimination) Gargoyle Gelatinous Cube
Ghoul Giant (Hill, Stone, Frost, Fire, Cloud, Storm) Gnoll Gnome
Goblin Golem (Wood, Bone, Amber, Bronze) Gorgon Gray Ooze
Green Slime Harpy Hellhound Hobgoblin Hydra Invisible Stalker
Kobold Leech, Giant Lizard Man Lycanthrope (-rat, -wolf, -boar, -tiger, -bear)
Manticore Medusa Minotaur Mule Mummy NPC Party Ocher Jelly
Ogre Orc Owl Bear Rat (N, G) Rhagdessa Rust Monster Scorpion, Giant
Shadow Shrieker Skeleton
Snake (Spitting Cobra, Giant Racer, Pit Viper, Giant Rattler, Rock Python)
Specter Spider, Giant (Crab, Black Widow, Tarantella) Sprite
Stirge Thoul Troglodyte Troll Vampire Wight Wolf (N, Dire)
Wraith Wyvern Yellow Mold Zombie (No Ghost or Ghast)
Quite a list, 109 if my count is right. I think normal adventurers would know something about these.
