It’s that wonderful time when Bungie’s regular offering of high-reward Weekly Heroic and Nightfall Strike missions are rebooted (along with any raid progress made in the previous week), giving everyone a fresh chance at scoring some of the game’s sweetest and rarest loot.

 Are you new to Destiny? Don’t know what any of this means? Good news! There’s a Destiny wiki that’s packed with information. Click on through for details on what Strikes are, and how Nightfall differs from Weekly Heroic challenges.

Do things feel a bit… familiar this week? They should. Not only does the rainbow burn return for the third week in a row, but the week’s chosen Strike — Winter’s Run — is the same one that ushered in the first of these consecutive rainbow burns. Thankfully, this is an easy Strike under normal circumstances, and rainbow burn makes it laughably so. Read on for the rundown….

Nightfall

• Epic – This is a standard Nightfall modifier. It just means there are more enemies to fight, and a greater number of Majors (the yellow health bar dudes) on the field.
• Nightfall – Another standard Nightfall modifier. This one boots the entire Fireteam back to orbit if everyone is downed inside one of the revive-only respawn Darkness Zones.
• Arc Burn – Big damage boost for all weapons that deal Arc damage (blue electricity symbol).
• Solar Burn – Big damage boost for all weapons that deal Solar damage (orange fireball symbol).
• Void Burn – Big damage boost for all weapons that deal Arc damage (purple swirly symbol).

Weekly Heroic

• Heroic
• Void Burn

“Rainbow burn” means that all three of the Nightfall modifiers give damage boosts — for you and your enemies — to all three forms of elemental damage in Destiny. The elements are color-coded, so it’s purple blasts for void damage, blue for arc damage and orange for solar damage. The same goes for shields; the hulking Vex Minotaurs have purple shields that you can bring down rapidly with void-infused weapons.

When it’s rainbow burn, any of the three elements do boosted damage (though shields still fall more quickly when they take fire from the same element). Bring along any primary weapons that you’ve collected from raids, as they’re the only primaries in Destiny that dish out elemental damage.

The same recommendations from last time stand. Atheon’s Epilogue and Word of Crota are handy because their void damage cuts through the many Minotaurs you encounter during Winter’s Run. And for the final boss fight, Fang of Ir Yut, Fatebringer, Oversoul Edict, Praedyth’s Timepiece and Nechrochasm are useful for decimating the arc shields protecting Fallen Captains. If you’ve got more than one of those, go with Fang or Fatebringer.
