You utter a word of power and command one creature you can see within range to die. The creature must make a constitution saving throw. On a failed save, the creature has vulnerability to all damage for 1 minute. If the creature is reduced to 100 hit points or fewer during this time, it dies and can't be revived except by a wish spell or greater magic. If the creature has resistance or immunity to a damage type, it is treated as not having that resistance or immunity for the duration of the spell.
