1 For a group of mixed sizes, apply only the modifier for the largest size category.
You are skilled at surviving in the wild and at navigating in the wilderness. You also excel at following trails and tracks left by others.
Check: You can keep yourself and others safe and fed in the wild. See Table: Survival DCs by Task for DCs for various tasks that require Survival checks.
To find tracks or to follow them for 1 mile requires a successful Survival check. You must make another Survival check every time the tracks become difficult to follow. If you are not trained in this skill, you can make untrained checks to find tracks, but you can follow them only if the DC for the task is 10 or lower. Alternatively, you can use the Perception skill to find a footprint or similar sign of a creature's passage using the same DCs, but you can't use Perception to follow tracks, even if someone else has already found them.
You move at half your normal speed while following tracks (or at your normal speed with a –5 penalty on the check, or at up to twice your normal speed with a –20 penalty on the check). The DC depends on the surface and the prevailing conditions, as given on table.
Very Soft Ground: Any surface (fresh snow, thick dust, wet mud) that holds deep, clear impressions of footprints.
Soft Ground: Any surface soft enough to yield to pressure, but firmer than wet mud or fresh snow, in which a creature leaves frequent but shallow footprints.
Firm Ground: Most normal outdoor surfaces (such as lawns, fields, woods, and the like) or exceptionally soft or dirty indoor surfaces (thick rugs and very dirty or dusty floors). The creature might leave some traces (broken branches or tufts of hair), but it leaves only occasional or partial footprints.
Hard Ground: Any surface that doesn't hold footprints at all, such as bare rock or an indoor floor. Most streambeds fall into this category, since any footprints left behind are obscured or washed away. The creature leaves only traces (scuff marks or displaced pebbles).
Several modifiers may apply to the Survival check, as given on Table: Survival DC Modifiers.
Varies. A single Survival check may represent activity over the course of hours or a full day. A Survival check made to find tracks is at least a full-round action, and it may take even longer.
Varies. For getting along in the wild or for gaining the Fortitude save bonus noted in Table: Survival DCs by Task, you make a Survival check once every 24 hours. The result of that check applies until the next check is made. To avoid getting lost or avoid natural hazards, you make a Survival check whenever the situation calls for one. Retries to avoid getting lost in a specific situation or to avoid a specific natural hazard are not allowed. For finding tracks, you can retry a failed check after 1 hour (outdoors) or 10 minutes (indoors) of searching.
