It is unavoidable. Pretty much every monster has some sort of weakness, special ability, etc. that wouldn't be known by every PC. That's a major distinction. You guys aren't avoiding such scenarios, either. You're just okay with metagaming.Sure they have. I mean, I get that you’re saying that’s not their intentionally creating the scenario in order for metagaming to occur… but it’s unavoidable based on the circumstances, so it’s not really much of a distinction.
I'm going to look at A in the MM.It absolutely is. Use a monster that doesn’t require exploitation of a player-known vulnerability. Don’t use one that does.
Aarakocra: Special ability Dive Attack.
Aboleth: Lots of specials.
Angels: Lots of specials.
Animated Objects: Has specials.
Ankheg: Acid Spray.
Azer: Specials.
So according to what you just said, I can't use anything in the MM under A. The rest of the letters are just as bad. I mean, I guess I can use ogres. No, wait. They have darkvision which might not be known by everyone. I guess I can't use any monsters.
Forget troll. Troll is just the poster child. Vulnerabilities aren't the issue. Out of character knowledge is the issue, so any special ability, resistance, vulnerability, special movement type, etc. is metagame fodder.You are if the selection of a troll is coupled with a GM desire for the players to behave as of their characters don’t know about the fire vulnerability. That’s why I included both those elements in my “equation”.
It’s not the selection of the troll alone that is the issue. It’s the selection of the troll combined with the GM’s need for the players to not metagame.
I use trolls all the time with no issue. But if I had some need for the players to pretend they don’t know what they know, then I’d choose another monster.
