Earlier this month, Delta wrote a post about wilderness movement rules in AD&D. I like the idea of modelling wilderness movements in terms of a budget (based on mode of locomotion) that can be “spent” to enter adjacent hexes. (This is also the way Fourth Edition does tactical movement.) The important conceptual work is all in Delta’s post, but I want an easily gameable set of rules that I can apply to my 6 mile hex maps based on the B/X wilderness movement rules (the relevant references are Labyrinth Lord page 45, the Expert rulebook page X19, and the Rules Cyclopedia page 88).
The base budget is calculated by doubling the normal “inches per turn” movement rate. So a standard human movement rate of 12 translates to 120 feet per turn and 24 miles (or 4 hexes) per day of clear ground. Each movement point ends up being worth one mile of travel on clear ground, which is nice.
|Locomotion Mode||Movement Budget|
|Human, lightly encumbered||18|
|Human, heavily encumbered||12|
|Riding horse, unencumbered||48|
|Riding horse, lightly encumbered||36|
|Riding horse, heavily encumbered||24|
(See the LotFP encumbrance rules for what it means to be encumbered.)
|Terrain||Examples||Movement Cost||Becoming Lost|
0 in 6
|Average||clear, city, grasslands, trail *||
1 in 6
|Moderate||forest, hills, desert, badlands||
2 in 6
|Difficult||mountains, jungle, swamp||
3 in 6
* There is no chance of getting lost when following a trail if the trail is well-known.
Delta suggests that for added realism different modes of transport might have modifiers when moving over some terrain types (he gave the example of cavalry over mountains). I agree, but I’m not going to systematize that. I think individual rulings for specific situations will be good enough. These calculations are all behind the screen, so players will not be thinking in terms of movement budgets. At least, that’s how I foresee this. We’ll see how it works in practice.
Awesome! Hope you don’t mind, but I riffed off of this on my own blog. It was just to juicy to pass up! Simple and elegant…
For ease of reference:
I thought about doing that, but did not want to impose or appear like I was pimping my own blog more than I already had by mentioning using it.
I like this. I will be modifying this for my purposes and including it in my game. Thank you!
Great! I would like to hear how it works out.
Doubling the inches per turn is how Gygax did it on page 102 of the AD&D Players Handbook.
Brilliant. I so PDF’d this!
Thanks! I’ve actually moved to a slightly simpler procedure myself recently, but if I was going to count exact distances, this would definitely be the method I would use, still.
