Power Word Stun

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. Power Word Stun: You utter a single word of power that instantly causes one creature of your choice to become stunned, whether the creature can hear the word or not. The duration of the spell depends on the target's current hit point total. Any creature that currently has 151 or more hit points is unaffected by power word stun.
