Take a Hike
Very rare1.9%ObjectiveOptionalSingle-player
Traversed the canyon without a Phaeton in Reunion on Heroic difficulty.
Reunion gives you a Phaeton to fly across a canyon - instead, cross it on the ground the whole way, on Heroic. Skip the aircraft and traverse manually. Slower and riskier on Heroic, so clear enemies methodically as you go; a lower-difficulty run won't count.
