As a player, do you think you have fought every monster in the Monster Manual? Or as a DM, do you think you have you used every monster in the Monster Manual? If not, what sort of percentage do you think you have used/fought? And do you keep any sort of log?
These are questions that interest me.
If you’re familiar with Pokémon, you’ll probably know about the Pokédex. As you play the game you keep a log of all the monsters you have seen and captured and one of the goals of the game is to “complete” it, (for example, in the original game there are 150 monsters to capture).
I’m two sessions into DM’ing a new D&D campaign, and one of my goals is for my players to encounter as many different creatures from the Monster Manual as possible. As they are all new to the game I especially want them to encounter the classic D&D monsters (so Dragons, Beholders, Gelatinous Cubes, Mind flayers, Owlbears etc etc).
So I thought it would be fun to keep a log on here of the monsters they encounter from session to session. If other players/DMs get involved too, I think it will be fun to compare stats and see which monsters are particularly popular. I’ll be sticking to the Monster Manual, but you don’t have to. I did a quick count of the number of monsters in it and came to 396. (That’s including the beasts at the back but not the NPCs. And counting the 4 ages of each dragon type together.)
So with that number, we can start tracking our monsterdexs. Even if you’re midway through a campaign, you can still take part, either start counting from your next session or list out all the monsters you or your players have encountered so far, (that you can remember, at least). Feel free to comment and discuss too
