Advanced Dungeons & Dragons: Monster Manual II (part 1)
Steve: One of the coolest things about old school D&D were the ridiculous numbers under "NO. APPEARING." That's 12d12 Monodrones.
Zack: I remember playing D&D once when we encountered 15 orcs or goblins. It took ten minutes just to figure out the order in which everyone would attack. Imagine encountering 123 of them.
Steve: It should be your first red flag that whoever put this in the Monster Manual never intended for anyone to actually use them in a game.
Zack: Or whoever put the Modrons in the book was an autistic kook obsessed with huge random tables and square roots and rolling dice. Take your pick.
Steve: When you say huge do you mean medium?
Zack: I mean generating data tables that require you to roll three ten-sided dice.
