Destiny servers have been reset for another week and the new strikes along with their modifiers have been revealed.

Destiny Nightfall And Heroic - Weekly Reset | 24th March Watch on YouTube

This week's strike is The Summoning Pits on the Moon. For The Nightfall, the strike has Arc Burn as well as Lightswitch. The same burn is active on the Heroic strike too.

Arc Burn means that any Arc damage you take is increased, but it also means your Arc weapons deal more damage.
