Your legendary speed allows you to avoid nearly any area effect.
Benefit(s): Once per day, when you fail a Reflex save, you may choose to replace your saving throw result with 20 + your total Reflex save bonus (as if you had rolled a 20 on the d20 roll for your Reflex save, though this does not count as an automatic success). You must make this decision immediately after discovering your initial Reflex save failed. This benefit is in addition to (does not replace) the normal benefit of Improved Lightning Reflexes.
