The Sieve

Overview

The Sieve is a limited-time, 3-player endgame activity on Kepler introduced with The Edge of Fate. You protect Drifter's mining rigs as he collects dark matter in his Haul, repelling the House of Exile and the Vex.

How to launch

Complete the Edge of Fate campaign (Brave or Legendary difficulty) to unlock it. It runs on a rotation: open about 30 minutes, then about 90 minutes before it returns. Check the map near Caldera on Kepler; interact with the marked console to begin. Enemies spawn about 15 power above your fireteam's highest level.

Mechanics

1. Set up the mining drill at the marked area and defend it while it runs.
2. Complete objectives and collect the chest after each round.
3. Alternate rounds feature bosses (some evasive, some with shields; sabotage Minotaurs can shut the mining down).
4. The final Dark Matter Bonanza round drops motes from enemies; deposit them to shatter Oracles for extra chests.

Rewards

Each round chest gives Kepler gear and Fated Ciphers (used at the Altar of Relativity). Attuning to an item type raises its drop chance.
