Flame Strike

At 3rd level, and every two levels thereafter, a sorcerer learns an additional spell, derived from her bloodline. These spells are in addition to the number of spells given at new levels. Flame Strike: A flame strike evokes a vertical column of divine fire. The spell deals 1d6 points of damage per caster level (maximum 15d6). Half the damage is fire damage, but the other half results directly from divine power and is therefore not subject to being reduced by resistance to fire-based attacks.
