Wu jen are mysterious spellcasters of the far east who draw on the power of the five elements (earth, fire, metal, water, and wood), command spirit forces, and seek to expand their knowledge of the world, both magical and mundane. Typically, they live as hermits in the wilderness, purifying their bodies and minds to contact the various natural and supernatural powers. It is from these entities that they learn their spells and magical means to control the invisible forces of the world.
The wu jen has the following class features.
A wu jen adds the spells from the five elemental schools (earth, fire, metal, water, wood) to his spell list. A wu jen otherwise learns, prepares, and cast spells as an arcanist equal to his level.
Elemental Focus (Su)
A wu jen draws his power from the five elements. At 1st level, a wu jen chooses an elemental school of magic; earth, fire, metal, water, or wood. The wu jen gains the abilities granted by that school, as the elelmental school class feature of the wizard, treating his arcanist level as his wizard level for these abilities. In addition, the wu jen can prepare one additional spell per day of each level he can cast, but this spell must be chosen from the selected elemental school.
