i ' d need to roll for litterly everything , cause i have no fucking clue what my character knows , im not him . I think a lot of things can be gleaned from the character ' s background . If a character was a wizard studying magical creatures , or if the creature is from an areaclimate that the PC live in , it may be reasonable for them to know a creature ' s resistances . Things like that I will make a judgment call and my players are usually happy with it , otherwise they can roll . I think the OP ' s situation is more like having a split party in different physical locations and they all act like the information they learned separately was automatically shared telepathically between them . <| sep |> That ' s it , thanks ! I wondered if it was a mutation at first .
