*Once in the dungeon, a new game begins.* When the party enters a large dungeon, GMs collect the party's Crawl Strategy to prepare for an extended crawl: ♦ What is the Marching Order? ~~♦ What is the Default Initiative?~~ ♦ How are they handling Visibility? ♦ What is each member's Passive Perception? The GM shares the dungeon's General Features with the party, such as: ♦ The dungeon's Construction Material. ♦ The dungeon's Ceiling Height. ♦ The dungeon's Lighting. This initial exchange of information both saves time and produces more accurate results. **Time Saved.** If the crawl strategy is left vague, it's possible that arguments arise about every given edge-case. **Accurate Results.** Adhering to an agreed upon strategy feels fair when inevitably things go sideways in the dangerous dungeon. ## Crawl Strategy Once you've collected the party's crawl strategy, reference these segments on how it relates to the crawl as a whole. ### Marching Order Ask the party to determine their marching order by deciding who's first, who's last, and order the rest of the party in between. **Single File.** A dungeon with 5-foot-wide corridors should be explored by a party with a single-file marching order. **Double File.** A dungeon with 10-foot-wide corridors should be explored by a party with a double-file marching order. >[!note] Whenever there's a question, we'll default to Double File. ### Visibility Most dungeons are dark and unlit places, making it important to determine how the party is handling visibility. **Determine Light Sources.** Ask the party which of them are carrying light sources, and what these light sources are. Make a note of those light sources and how long they last on the Stretch Tracking Sheet (pg. 47). **Darkvision.** For party members with Darkvision, make a note of which characters can see in the dark and at what range. >[!warning] >Keep in mind that characters with darkvision still make Perception checks at disadvantage in the dark, which decreases Passive Perception by -5. ### passive Perception Passive Perception simplifies how monsters that utilize stealth approach the party. Ask the party their passive perception score and note it down. **Lower than 15.** Characters with a Passive Perception score lower than 15 won't spot hidden creatures unless they make an ability check, since hiding requires a DC 15 Stealth check. **15 or Higher.** Characters with a Passive Perception score higher than 15 can spot hidden creatures. Make a note of the exact score, since it may well become important for running monsters that rely on stealth.
