Forgotten Gambler

One of my entries for Seventh Sanctum's Class Act contest. This is the Forgotten Gambler of the Earth Goddess.
Long ago, there was a great and wise earth goddess whose name is now lost in the mists of time. She selected certain champions with which to surround herself and gifted them with great talents and skills. The requirements for joining the ranks of her chosen were stringent, but the rewards were great. She offered them wonderful powers and near-eternal life. Being an earth goddess, she forbade her followers from slaying any form of intelligent life and bid them be wary of injuring any sentient being. They chose instead to challenge those who would insult their deity using only contests of luck and skill, playing for high stakes. They became reknowned throughout the land and many adventurers traveled far and wide for a chance to challenge this legendary order, hoping to gain great rewards and perhaps even a chance to join their ranks.
As time wore on, however, their fame dwindled, as did the number of worshipers of their goddess. Their woodland temple was forgotten as the wilderness around it grew more twisted. The immortal gamblers locked themselves away in this sanctum, growing ever more weary of their eternal life as time wore on.
The requirements to become a Forgotten Gambler of the Earth Goddess are as follows. By nature, they depend on luck, chance, and chaos, and hold all life in highest respect, so a Forgotten Gambler must always be Chaotic Good. They must be skilled in sleight of hand and have formidable dexterity. In addition, they must be in possession of sufficient wisdom to use the spells granted by the earth goddess. Finally, the aspiring Forgotten Gambler must make a pilgrimage to the hidden forest temple, deep within a fiend-infested, trackless forest, and defeat one of the ranks of Forgotten Gamblers in a contest of skill, chosen by the challenged party. This is easier said than done. Minds honed by unnaturally long lives, the Gamblers have had a long time to devise their devious and cunning mind games, alone in the forest. Finally, the pilgrim must spend some time in prayer to the earth goddess and swear him or her self to service forever. At that point, he or she will be welcomed into the ranks of the Forgotten Gamblers.
At level one, the new Gambler gains the ability to turn aside or rebuke any undead creature by channelling the good energy of his or her deity. He or she also gains the ability to cast cleric spells. The Gambler also gains at this point an increase in luck, making chance a major factor in deciding the outcome of any of the Gambler's undertakings. Finally, the Gambler is required at some point during his or her first level to go on a vision quest to discover a spirit animal companion. This spirit animal takes the form of a woodland creature of the Gambler's choosing and will add its skills to the Gambler's own.
