Bull's Strength

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. Bull's Strength: The subject becomes stronger. The spell grants a +4 enhancement bonus to Strength for 5 minutes, adding the usual benefits to melee attack rolls, melee damage rolls, and other uses of the Strength modifier. Enhancement bonuses do not stack with other enhancement bonuses, for example with bonuses from belts.
