You gain resistance to that damage type for the duration of the spell.

Energy Redirection: When you take damage of the chosen type, you can use your reaction to choose one creature you can see within 30 feet. That creature must make a Dexterity saving throw against your spell save DC, taking 4d6 on a failed save, or half as much damage on a successful one. The redirected damage is of the chosen type.
