The Weekly Nightfall Strike is the same as the Weekly Heroic Strike, but upped to level 30 and with many mission modifiers including Epic and Nightfall. Possible rewards for completing this Strike include Legendary or Exotic equipment, Strange Coins or 6-12 Ascendant Material. Weekly Nightfall Strikes are unlocked once a Guardian reaches level 24. Completing the Nightfall Strike rewards your Guardian with a buff called "Radiant Light," represented by a blue, flaming animation around their head, that increases all XP and reputation gains by 25% until the weekly refresh.
