The House of Wolves add-on also adds a new weekly wrinkle, in the form of Prison of Elder. The multi-round gauntlets are built for endgame play, with the specific enemy types and modifiers changing from week to week.
Arc Burn - All Arc damage is increased.
Small Arms - Primary weapons do increased damage.
Winter's Run is one of Destiny's shorter Strikes, with very little ground to cover between the spawn point and the first Darkness Zone, and then a similarly short distance separating that first Darkness Zone from the boss encounter. This particular Nightfall is especially appealing because of the great modifier synergy. Elemental "burns" are always a welcome sight, but the idea of pairing Arc/Solar Burn with Small Arms is particularly tantalizing.
Brawler- Guardian melee damage is increased by 300%.
For the second week in a row, you'll need to have one of Destiny's optional add-ons to participate in the Weekly Heroic Strike. This time it's The Dark Below Strike, The Will of Crota. This one's a bit of a grind, both in terms of length and challenge level. Brawler promises to be handy during the final phases of the mission when Hive melee knights start rushing in. Even better, the Brawler modifier doesn't give your enemies a boost, and that's always welcome.
