I am playing in a campaign I made myself using homebrewed rules based on a German pen-and-paper RPG called Das Schwarze Auge (DSA; The Dark Eye in English).
I have a very intelligent character in my group, who easily outsmarts any other player characters, but can't do much with his intelligence.
- I have tried to limit certain riddles/tasks to a minimum intelligence, but that feels extremely bad for other players, who have to stand by and watch. (None of my player characters are really stupid, but there still is a huge gap between let's say a pirate and scholar)
- I have tried to give the guy playing the smart character a note with hints when the group faces a difficult riddle, but aside from opening the note and reading the hints there won't be any sense of pride and accomplishment (hah, accidental EA) for the player, because he didn't actually do something but pass my notes.
- I have tried to make him speak more 'learned' than other characters, but this was extreme hard for my group to role play.
- I have tried to give him bonuses like being able to ask me for knowledge on certain things (like vague monster stats, weak points of armor etc.), but there were very few thing this character should know better than another character (e.g our blacksmith or our hunter) in this group, just because he is more intelligence, but not familiar with the profession.
How can I help a smart character to put his intelligence to a good use without forcing my other players to 'act stupid' simply because their chars only have average intelligence?
