The Sieve Boost

• Runs of The Sieve, 1 to 10, set under Number Of Runs.
• Extras: Self-play (Sherpa).
• The Kepler weapons, armor and Exotic armor chances from each run.

Each run is a defence of Drifter's rigs against two factions, with bosses that count toward Stitchripper. Exotic armor is a chance per run, not a fixed drop. The game points to The Sieve as a main source of Fated Ciphers, which are spent to focus Kepler gear. Work starts in about 30 minutes; one run usually takes about 1 hour.

Kepler is the destination that came with The Edge of Fate in July 2025, and The Sieve is one of its activities. The enemies are Eliksni of the House of Exile and the Vex, both fighting over the anomaly Drifter is mining.

• The Edge of Fate on the account, since The Sieve is on Kepler.
• A character with enough Power for the difficulty you want the runs on.

How many players?

Up to three, the activity's fireteam size.

Does every run give Exotic armor?

No, it is a chance per run.

Does Stitchripper need many runs?

It counts bosses defeated in The Sieve, so it builds up over several runs.

Who runs the Haul?

Drifter, better known as the Gambit vendor in the Tower, who is mining dark matter from Kepler's anomaly here.
