What are your lifts ? <| sep |> Your first suggestion doesn ' t do much against metagaming . Yes , you ' re making it harder to work , but people will always choose to metagame in that case . They either do nothing at all or have a chance at helping your friend metagamers is that a term ? will choose the chance always . Your second suggestion is more subtle and punishes metagaming , but it ' s possible that the player will think that it was going to happen anyway . It could do nothing or even encourage metagaming unless you directly tell the player you got robbed because you metagamed . I personally prefer explaining metagaming in character , although it mostly applies to knowledge . You know that Trolls don ' t like fire because you ' ve heardread it somewhere . Considering that the characters live in a dangerous world , it ' s more than possible that they ' ve heard a story from a bard or read a novel . Going back to the example of getting attacked while taking a piss roll a stealth check for the bandits , potentially at advantage and contest their stealth with a perception roll from all characters , made with disadvantage if they ' re sleeping . Essentially remove the potential metagaming by allowing a roll beforehand . If the DM is generous and doesn ' t fuck around with playerscharacters , maybe the players won ' t see the need to metagame in the first place .
