Camouflage

  	By using this proficiency, the character can attempt to conceal himself, his companions, and inanimate objects by using natural or man-made materials. Successful use assumes the availability of all necessary materials. In forests and jungles, the character can use shrubbery, mud, and other readily available resources. Arctic or similarly barren terrain usually requires special clothing, paints, or other artificial materials (although "digging in" is an old trick which may be applicable in such terrain, depending on local conditions). It takes a character a half-hour to camouflage himself or another person, two or three hours to conceal a cart or inanimate object of comparable size, and a half-day to hide a small building.
  	Neither human, demihuman, monster, nor animal passersby will be able to see a camouflaged character, presuming the character makes a successful proficiency check. Camouflaged companions will also go unnoticed; only one proficiency check is required for the entire group.
  	Objects may also be camouflaged. Objects the size of a person require no penalty to the check; cart-sized objects require a -1 penalty, while building-sized objects require a -3 penalty. The DM may adjust penalties based on these guidelines.
  	Camouflaging has no effect on predators that locate prey by scent or other keen senses; a hungry wolf can still sniff out a camouflaged human. A camouflaged person has no protection against a passerby who accidently brushes against or bumps into him. Likewise, a camouflaged person may reveal himself if he sneezes, cries out from the sting of a bee, or makes any other sound.
  	Note that camouflaging is only necessary for persons or objects that would otherwise be partially or entirely exposed. A person hiding behind a stone wall wouldn't need to be camouflaged to avoid detection, nor would a buried object.

Foraging

  	By using this proficiency, a character can search a wilderness area to locate a small amount of a desired material, such as a branch suitable for carving into a bow, enough kindling to start a fire, a medicinal herb, or a component required for a spell. The character must spend 2-8 (2d4) hours searching, and the material must theoretically be available in the area being searched (for instance an icicle isn't available in the desert, nor dry kindling on the ocean floor). The DM doesn't confirm if the material sought is actually available until after the character has searched for the designated period. If the DM decides the material isn't in the area, no proficiency check is necessary; he merely reveals that the search was in vain.
  	If the DM decides the material is indeed available, a successful proficiency check means the character has found what he's been looking for. As a rule of thumb, the character locates no more than a handful of the desired material, though the DM may make exceptions (if searching for a few leaves of a particular herb, the character may instead find an entire field).
  	If the check fails, the material isn't found. The character may search a different area, requiring another 2-8 hours and a new proficiency check.

Spelunking

  	A character with this proficiency has a thorough understanding of caves and underground passages, including their geology, formation, and hazards. The character generally knows what natural hazards are possible and what general equipment a spelunking party should outfit itself with. A successful proficiency check can reveal the following information:
•	Determine, by studying cracks in the walls and pebbles on the floor, sniffing the air, etc., the likelihood of a cave-in, flash flood, or other natural hazard. This only works with respect to natural formations, and is negated if the natural formations have been shored up, bricked in, or otherwise tampered with.
•	Estimate the time required to excavate a passage blocked with rubble.
While exploring extensive underground caverns, a successful check reduces the chance of getting hopelessly lost when confronted by multiple unmarked passages, sinkholes, etc. to a maximum of 30%, assuming good lighting (see DMG Table 81-82).

Trail Marking

  	By notching trees, scattering pebbles, piling stones, and clipping weeds, the character can mark a trail through any wilderness area. Providing he moves at 2/3 his normal movement rate, he can mark a continuous trail as long as he likes; however, the longer the trail, the less likely he'll be able to follow it back.
  	A successful proficiency check enables a backtracking character to follow his own trail for a distance equal to his level in miles. If he fails a check, he loses the trail. For instance, assume a 3rd level character marked a 12-mile trail. His first successful proficiency check enables him to follow this trail back three miles. A second successful proficiency check means he can follow the trail another three miles. The third check fails, and he loses the trail; he's only been able to follow his trail for a total of six miles.
  	The tracking proficiency isn't necessary to use the trail marking proficiency. However, when a ranger loses his own marked trail, he may still attempt to follow it using his tracking proficiency. Any other characters with the tracking proficiency may also attempt to follow a ranger's marked trail, using the rules applicable to the tracking proficiency.
  	A marked trail lasts unless it is obscured by precipitation, a forest fire, or the passage of time (an undisturbed trail marked in a forest should last for weeks, while an arctic trail may last less than a day during periods of heavy precipitation; the DM decides). A ranger or other character with the tracking proficiency may still attempt to follow an obscured trail using the tracking rules.

Trail Signs

  	A character with this proficiency can read symbolic messages indicated by an arrangement of stones or other physical objects. The character must designate the method of leaving messages preferred by his family, tribe, or culture. Typical methods include piling rocks, stacking branches, or building snow sculptures. When the character encounters such a message, he understands the meaning if he makes a successful proficiency check. ("A dragon dwells in these woods." "Eat the green berries for restored health.") The message is meaningless to characters without the trail signs proficiency. A character with the trail signs proficiency who uses methods other than the one encountered can try to read it at half the normal chance for success. This proficiency can also be used to identify the cultural group or tribe that has left a specific trail sign.

Veterinary Healing

  	The character can attempt to heal all types of normal animals, following the same procedures described in the description of the healing proficiency (returns 1-3 hit points if done within one round of wounding, once per creature per day; continued care can restore 1 hit point per day during non-strenuous traveling for up to 6 creatures; gives a +2 to save vs. poison if treated for 5 rounds within a round after poisoning; diagnose disease, magical origins identified, natural diseases take mildest form and shortest duration). Supernatural creatures (such as skeletons or ghouls) or creatures from another plane (such as aerial servants or xorn) cannot be treated with this proficiency.
 	 This proficiency is not cumulative with the healing proficiency--the first used will take precedence. The veterinary proficiency can be used on humans, demihumans, and humanoids at half the normal chance for success.

Weaponsmithing, Crude

  	This proficiency allows the making simple weapons out of natural materials. This skill is most often found in those from a primitive, tribal, or savage background.
  	The crude weapons are limited to natural materials: stone, wood, bone, sinew, reed, and the like. Crude weapons take a certain amount of time to make. The DM may add additional primitive weapons to the basic list.
  	The chance for success is based on the character's Wisdom, with a -3 penalty. Any warrior or a character with the hunting proficiency has a +3 bonus. The fashioner must be proficient in the use of the weapon.
  	If successful, the weapon can be used normally. If failed, the weapon is so badly flawed as to be useless. On a roll of 20, the weapon seems sound, but will break upon first use. On a roll of 1, the weapon has no chance of breaking except against a harder material.
  	Optional: Crude weapons check for breaking upon inflicting damage; roll 1d6. Bone weapons break on a roll of 1 or 2, stone weapons break on a roll of 1.
