Elemental

Among Shaman, those whom call themselves Elemental are those who chose the powers of Storms and Lightnings to strike their enemies down. Like other Shaman they also have powerful spells attuned to the waters, to the earth and to the flames to aid them in their fights. Shaman can also bind elementals to their will, using them against their enemies for short periods of time.
