I think it's non-trivial to mention that, in a pinch, I've used this with my cleric when I feel like my move action will result in a reflex save. There have been a few times, mid-combat, etc. when I realized that my move action would likely trigger a trap the rogue missed, etc. My reflex saves having advantage was huge. As reflex is not usually a nice buff stat for clerics, it's a neat perk that can save you from getting skewered by poison darts, falling axe, etc. Less efficient than your traps being disarmed before combat, but awesome for very specific circumstances.
