Consume Alcohol - This character has developed an incredibly high resistance to alcohol, being able to consume large quantities without much effect. He can consume twice as much for half the effect.

Deep Dive - A character with this proficiency can add 10 feet per round to his speed of descent when diving into the water, or from the surface. Thus, a character with the deep diving proficiency can descend 30 feet per round, plus modifiers for encumbrance, running start, and height. Likewise, a character with the deep diving proficiency can surface at a rate of 30 feet (not 20 feet) per round.  This proficiency provides characters with the ability to hold their breath for 2/3 their Constitution scores in rounds, not the 1/3 allowed to most characters. Effects of exceeding the allotted time are the same, regardless of proficiency ratings.

Endurance - A character with endurance proficiency is able to perform continual strenuous physical activity for twice as long as a normal character before becoming subject to the effects of fatigue and exhaustion. In those cases where extreme endurance is required, a successful proficiency check must be made. Note that this proficiency does not enable a character to extend the length of time that he can remain unaffected by a lack of food or water.

Jog - The character can move at twice his normal movement rate for a day. At the end of the day he must sleep for eight hours. After the first day's movement, the character must roll a proficiency check for success. If the die roll succeeds, the character can continue his running movement the next day. If the die roll fails, the character cannot use his running ability the next day. If involved in a battle during a day he spent running, he suffers a -1 penalty to his attack rolls.

Slow Respiration - A character with this proficiency has the ability to enter a deep trance and reduce the amount of air he needs to stay alive. To induce the trance he must be in a resting position, either resting, or lying down. After concentrating for one turn pulse and breathing drop well below normal (on a successful check if this fails the character cannot slow his breathing), so that breathing requires only 10% of the rate when resting. The character emerges from his trance at will, fully aware of anything that has occurred nearby.

Sport - This is the ability to play one specific sport at a professional level. This skill must be rebought for each additional sport.
