Base DC for foraging is 5-15, depending on the fertility of the area. On a success, the DM rolls 2d8 to determine how many meals the individual gathered. For every 5 points the the roll exceeds the DC, roll an additional d8.
Each attempt takes 6 hours.
When fishing, the DM must first determine the quality of the place the character chooses to fish. This is done by rolling 3d8, which sets the difficulty of the proceeding survival checks. The DC is further modified by the equipment that the character chooses to use. Finishing with your bare hands imposes a +2 difficulty bonus to the DC. If a character chooses to finish with a spear, the DC is unchanged. If a character has specialized equipment such as a net, or a hook and line, they gain a +2 bonus to their skill check, but if they fail by greater than 5 the equipment is damaged or lost.
On a success, the DM rolls 2d12 to determine how much meat the fish he has caught will yield. For every 5 points the the roll exceeds the DC, roll an additional d12.
Each attempt takes 6 hours.
Trapping is more complicated. Character must make a sub+MIND check to search for animal sign and trail to find possible trap locations in an area. Once trap locations are found, they do not have to be relocated. Base DC is 15. The GM rolls in secret to see if the trap goes off, when it does, and what it captures. Player success is taken into account. Traps remain in place until they are triggered and may be checked daily. Checking preset may be done in addition to foraging. Resetting a triggered trap is a Base DC10. You may check the traps set by others.
On average, the amount of edible meat provided by a fresh kill is about 1/2 the animals live weight. An approximate amount of meals that can be reasonably gained from an individual animal based on the following chart. All animals will provide at least one meal. It is not exact and should be taken as a generalization. Individual animals may yield more or less meat depending on other factors. Also note that animals are also sources of hide, bone, sinew, and other useful substances.
Code:
Size Meals Per Wound
Tiny 1d2-1
Small 1d4
Medium 2d6
Large 4d8
Huge 8d10
Gargantuan 16d12
Colossal 32d20
Butchering an animal take about three minutes per meal. It should be noted that predators often will attempt to claim the kills made by others, and that the smell and sounds of a kill are sure to attract the attention of any carnivores in the area. For this reason is suggested that they relocated the prey to a more secure area before doing so.
Most foods have a limited lifespan. Fruits will rot, vegetable will rot, and unless preserved most meat will decay to the point its inedible to even the most undiscriminating planet within a week. As such, preserving food is important. Instead of gathering, a character may instead spend the day preparing food. The base DC is 10 to preserve 2d6 meals. For every 5 points the the roll exceeds the DC, roll an additional d6.
Proper preservation equipment, such as drying racks or smoking rigs will add additional dice depending on their complexity. If the roll fails by more than 5 roll 2d6 to determine the number of meals rendered inedible in the attempt.
Cooking improved the quality of food and can stretch supplies. The base DC for cooking is 5, or the number of meals being prepared, whichever is higher. For every 5 levels of success starting at the first level, increase the final number of meals by 10%.
