Epic Star-Iron Reliquary

Chests & crates

Found behind a locked door in the Arcane Research Facility. Takes 15 days to open, then gives one Epic enchanted item (staves, wands, spellbooks and battlemage gear), $100,000, and sometimes a weapon attachment or a Masterwork part. You can open one crate at a time, plus one more for every crime category at mastery 100. Unopened crates can be sold on the item market.

Where to get it

• Endless Road delve: Arcane Research Facility, opening the locked door with the Star-Iron Key (10% of crates are this rarity). Trade it on the Item Market.
