Rare Royal Strongbox

Chests & crates

Found behind a locked door in the Ruined Castle. Takes 10 days to open, then gives one Rare enchanted item (knight armor, shields and swords), $40,000, 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: Ruined Castle, opening the locked door with the Royal Signet Key (30% of crates are this rarity). Trade it on the Item Market.
