Some factors can affect both the rate and effectiveness of exploration, as detailed below.

Careful Exploration: Some groups might choose to explore more slowly and methodically in order to make a more careful search. This allows the group to attempt one extra exploration check for each day spent in careful exploration, but it limits the total number of Discovery Points that can be gained to 1 (a character using careful exploration cannot earn additional Discovery Points by exceeding the DC by 5 or more). Typically, careful exploration can be performed only if the terrain is relatively clear and free of obstructions. The GM is free to limit this option if she believes that a slow search would not garner much benefit due to the terrain.

Darkness: Unless the explorer has darkvision or another ability to see in darkness, he takes a –4 penalty on exploration checks he attempts when some but at most half of the hours spent exploring that day occur after nightfall. Explorers take a –8 penalty on checks attempted when more than half of the hours spent exploring occur after nightfall.

Extending the Day: A day of exploration typically takes 8 hours; the rest of each day is assumed to be split between 8 hours of rest and 8 hours spent eating, making and breaking camp, relaxing, and the like. It’s possible to increase the amount of time in a day used for exploring by spending an additional 8-hour session exploring, but for every additional stretch of time up to 8 hours by which the PCs extend their time spent exploring, they take a cumulative –4 penalty on exploration checks to earn Discovery Points until they next rest for 8 hours. At the GM’s discretion, fatigue and exhaustion can also set in if the PCs don’t rest enough.

Weather: Inclement weather hampers exploration checks if it is the predominant weather of a given exploration period. For example, the PCs would take a –1 penalty in the case of light fog or light rain, but a –10 penalty in the case of a blizzard or hurricane.
