I feel like trolls are common enough that even a farmer would know they don’t like fire or acid. And yet, some DMs will make you roll a dungeoneering or other knowledge check to see if your adventurer knows.
Trolls are only common if they’re made common, though. Like, they’re common in the Forgotten Realms, or Golarion, or whatever, but commonality is out the window in a homebrew setting.
