Evade vs Blocked

By ninjaneer2, in Descent: Journeys in the Dark

Both the "Evade" (Subterfuge) and "Blocked" (Melee) feat cards are played when monsters make a successful attack against a hero, but the results are slightly different. "Evade" says "that monster's attack becomes a miss" where "Blocked" says "that monster's attack against you becomes a miss"

Does this mean that "Evade" makes the attack miss against ALL heroes (e.g. if it were a Hell Hound's breath attack), or just miss against the hero who played it?
