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 howNightfall differs from Weekly Heroic challenges.

Taste the rainbow! Destiny fans can’t ask for much more from their weekly challenge reset. There are shorter Strikes than Winter’s Run, which concludes with a knockdown brawl against a towering Archon Priest, but the three-way burn makes everything more fun. Here’s a rundown of this week’s modifiers:

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” is a term that Destiny fans use to apply to the rarely appearing Nightfall challenge that has the Arc, Solar and Void Burns attached to it. Where most Nightfall and Weekly Heroic modifiers are designed to make the going tougher, burns are a double-edged situation.

On the one hand, using a weapon bolstered by the specified element — in this week’s case, any of the three — comes with a massive damage boost. On the other, enemies can inflict that much more harm on you when their mode of attack aligns with the burn. So when there’s a rainbow burn, you’re taking a whole lot more damage from virtually everything, but you’re giving as good as you get.

Obviously, this is the week to bring along any of the raid primary weapons that you’ve picked up, since those are the only primaries that apply elemental damage. The Word of Crota hand cannon and/or the Atheon’s Epilogue auto rifle are good picks for Winter’s Run due to the abundance of void-shielded Minotaur enemies. Arc damage is also handy for the final showdown, so dust off the ol’ Fatebringer hand cannon, too.
