History of Dares of Eternity

Overview

Dares of Eternity is a six-player seasonal arena playlist added with the Bungie 30th Anniversary update. Launch it from the Eternity node on the destinations map by walking into the rift between Xur and Starhorse. The game data lists Standard, Expert, Master and Legend variants; sources describe a matchmade normal difficulty at power 1150 and a no-matchmaking Legend at 1320 with Challenging enemies (the database's 1100 light level may be older). Unlock via Eternity Beckons.

Structure

Two sections, each with two identical rounds, a mini-boss and a boss. Round one: kill everything; bring Barrier, Unstoppable and Overload mods for Champions. Activate the Wheel of Adversity to choose the enemy faction. Round two is objective based: kill a marked enemy for an object and use it on an invulnerable target or blight, or capture zones.

Bosses

The final boss depends on your door: Hive (two copies of Crota, killed with cleavers), Cabal (a champion, destroy shield generators) or Vex (Zydron, with keybearers and containment protocols). Calus and Eramis context is not confirmed by the sources I opened.

Rewards

Strange Favor reputation, Treasure Keys, Strange Coins and gear. A random Lightning Round can add three chests (Lightning Round). Consecutive runs build a streak up to 5 for extra Strange Favor.
