Bungie has reset Destiny's servers to kick off a new week with new strikes and another chance for you to grind Crucible and Vanguard marks.
For this week, Sepiks Prime will be your strike for Nightfall and Heroic. You'll have Arc burn and so will the enemies. Lightswitch - which greatly increases enemy melee damage, will be your bane for both strikes.
We're expecting the 1.1.2 patch to drop later today, so stay tuned.
