Challenge Mission

Challenge missions involve specific scoring objectives, such as holding out against progressive waves of enemies. The rewards may be experience, gold, and, for some missions in Guild Wars Factions, Luxon or Kurzick faction points, depending on completion and mission. You will see personal bests and high scores displayed within the game. In the Nightfall challenge missions it is possible to obtain the items required to change heroes' armor art, the probability of obtaining these items is suspected to increase with higher scores, however it is possible to obtain them even with low scores.
