I’ve found the “raise” mechanic in Savage Worlds to be particularly useful for procedural tasks that come up in wilderness campaigns. [Each raise in SW represents a multiple of four by which you beat the target number; if your die roll beats the target by 8, you get two raises, for example. Dice explode in SW, so raises happen a little more frequently than you’d think.]
With that in mind, here’s what I’ve been tinkering around with for our campaign.
Orienteering and Getting Lost
We’re using a 5-mile hex map to explore the world of Autumn Frontiers. When heading overland, the party announces their general destination for the day (“We’ll head south until we get to the abandoned watchtower and then camp for the night”), and then one player makes a single Tracking check. Generally this will be the character with the best Tracking stat, but I can imagine situations where other PCs may have to step up to the plate.
A success means they’re able to navigate a single hex and proceed on toward their destination, rolling again in the next hex. A raise means they get through one additional map hex — covering 10 miles, estimated very roughly, before rolling again. A further raise equates to another 5-mile hex covered, etc. It's possible, with a single incredibly lucky dice roll, to have the PCs to hike unmolested several dozen miles toward their destination without getting lost.
If the roll fails, the party is lost in whatever 5-mile hex they ended up in. The GM should describe the physical geography, especially if there might be a chance that the players could spy a landmark and thus orient themselves that way. This can either lead to more exploring to find a new route, or perhaps an overnight stay in the wilds before attempting orientation again the next day.
Foraging for Food
A success means the character hunts/scavenges/forages enough food to sustain himself for the day — in our campaign, this is going mostly going to mean wild game meat, because one of the characters took “Vegetarian” as a hindrance. Each raise allows the PC to feed one additional character for that day. Note that foraging — especially hunting — takes a significant amount of time and should definitely affect how fast the party can travel overland.
