Flain FAQ
How do I get the Flain armor set in Destiny 2?
Flain drops from Sundered Doctrine. Collect four of the five pieces to unlock the full set bonus.
How many pieces do I need for the set bonus?
Two pieces switch on the 2-piece perk and four pieces switch on the stronger 4-piece perk. Any combination of slots counts, so you can run four pieces of the set plus an exotic in your fifth slot without breaking the bonus.
What is the best artifact for a Flain build?
Flain pairs best with the Tablet of Ruin artifact this season, since both lean into sever, threadlings, healing. See the artifact mods page for the exact perks to run.
