Wilderness Adventuring (OSE SRD)

Overview

This is OSE's overland procedure loop: choose direction, test navigation, test encounter pressure, and resolve logistical drift over days rather than turns.

Daily Sequence

  1. Choose route.
  2. Check for losing direction.
  3. Check wandering monsters.
  4. Resolve travel observations.
  5. End-of-day upkeep.

Core Movement Rules

  • Overland miles/day: base movement divided by 5.
  • Terrain modifies speed.
  • Forced march increases distance but requires compensating rest.

Terrain Pressure Table

Terrain Class Lost Chance Wandering Chance
Clear / grasslands / settled 1-in-6 1-in-6
Barren / forest / hills / desert 2-in-6 2-in-6
Jungle / mountains / swamp 3-in-6 3-in-6

Procedure Notes

  • Base overland miles/day uses movement rate divided by 5.
  • Forced march adds 50% distance and creates a full-day rest debt.
  • Foraging and hunting are separate procedures with different time costs.
