At 9th level, an elemental master increases the energy damage done by her elemental attack to 1d8 points + 1d8 points per 2 arcanist levels she possesses. The type of energy damage is determined by the elemental attack. In addition, the range of her elemental attack increases to 60 feet (in the case of flame arc, a 60-foot line). This ability replaces the arcanist exploit gained at 9th level.
