As GM I'd accept that argument from a person with a smart enough player, but not from one whose intelligence attracts penalties and not from one whose background is from an island or at sea or a city rat

In some settings I might have monsters like trolls only in some parts of the world, so you're out of luck if you're not from those places unless you read a lot (and if my group is prone to metagaming, change the monster's weakness)
