Gelatinous Icosahedron

 While D&D combat has a pretty clear order of operations and economy of actions, outside of combat I've tended to play things fast-and-loose regarding sequence, timing, and number of actions. I wouldn't be at all surprised if many other DMs handle things similarly. There's nothing inherently wrong flying by the seat of your pants, if that works for you, but if timekeeping becomes a tangled mess and/or you have some very assertive players who tend to monopolize the game between combats while passive ones barely get a chance to participate, a more structured exploration sequence may help. The editions I've played (B/X and BECMI, mostly) do give some guidelines, but for most of my DMing career I've struggled with how to apply them. Below is a more detailed, but still hopefully simple, step-by-step procedure for dungeon crawling. 1. Party moves, either until its exploration movement rate is exhausted or a keyed location or other point of interest is reached.  2. Des

In a game sense, they keep play
