Additional action + no exhaust is sexy since you can continue using that action to evade consecutively, and still have actions to move away. Managing to evade but unable to make some distance and getting caught up again feels bad and that is more likely with more enemies. If a ready enemy is waiting at the next location, you can continue surfing it and get an action to move away yet again a few times. Very reassuring spell for non-fighter that can dip into or , you save engage action for the fighter and your own action at the same time.
I have just tried with Daisy Walker and it has some nice synergy with Encyclopedia play as if succeed, it restore AoO-free state for her to use her free tome and get to work with full 3 actions of Encyclopedia boost, all while dropping engagement for the fighter. It just clicks...
