Evasion
9th-Level Ranger Feature
Beginning at 9th level, you can nimbly dodge out of the way of
certain area effects, such as a red dragon’s fiery breath or a
lightning bolt spell. When you are subjected to an effect that
allows you to make Dexterity saving throw for only half
damage, you instead take no damage if you succeed on the
saving throw. You take only half damage if you fail.
