There are many procedures out there but I wanted something simple and compatible with the B/X OSE ruleset. I took inspiration from many blogs, reddit posts and zines to come with my version of the hexcrawl rules.
I use the classic 1 HEX = 6 miles = +/- 10 km but it works with any size
Roll for Weather once each day
Watches
The day is divided in 3 watches of roughly 8 hours:
Early watch (+/- 6 am -> 2 pm)
Late watch (+/- 2 pm -> 10 pm)
Night watch (+/- 10 pm -> 6pm)
For each watch the party has one action
• TRAVEL: The party travels thru hexes.
Progress up to half of daily travel distance
all obvious locations/features and the terrain type of neighbouring hexes are revealed accordingly to sight distance.
Check for losing direction.
Roll on the Event Table
• EXPLORE: The party search for hidden features within the current hex.
One Location/Feature is discovered.
Roll on the Event Table.
• SUPPLY: The party is gathering food and water
Hunting and foraging according to OSE (1 in 6 chance)
Roll on the Event Table.
• CAMP: The party stops to set up camp.
Each member removes 1 of penalty due to fatigue (if any)
Roll on the Event Table.
• INTERACT: The party interacts with a location/feature
Dungeon delving, town/village adventure, lair exploration, long Npc interaction, ...
Fatigue
Every night the party skips camp or each watch they do a forced march they get a cumulative -1 penalty on all their checks.Event Table
• ENCOUNTER: generate a random encounter. If the distance is far it can be an omen.
• LOCATION/FEATURE: The party stumbles upon a hidden location or feature
• HAZARD: The party comes across a hazard or impediment (Event or Terrain at DM discretion)
• QUIET : Nothing noticeable happens.
