From Diablo Wiki
Escape skills refer to abilities in Diablo III that allow characters to survive experiences that would have been fatal without that skill. "Escape" can apply to skills that physically move the player out of harm's way or from an attacker's clutches such as with Jailer or Waller or momentarily protects them from harm so they can attempt to kill their attacker first. They are 'panic buttons' in effect and every class has them.
