One of my players is a bit of a puzzle fanatic. Since he's built a severely sub-optimal character for combat, I'm thinking of throwing in the occasional puzzle so he can shine on those while the other player still gets to shine when they kill big things. Any suggestions for some simple to run puzzles to throw at them(I'm thinking no more than one a dungeon when it's appropriate)?
I've got one figured out for this week. It's a variation on one I saw in the NWN Kingmaker module. They get 6 different colored gems and there are six receptacles. They then get a small number of clues(I'm thinking 4-5) about the relative locations where the gems need to be placed(the module had things like "the red fires burned north of the green trees"). The variation is mostly in that I'm not going to make them find the gems elsewhere in the dungeon, just have them be in a box in the room.
So, any other suggestions I can throw into later dungeons?
