How Barrows drop odds work

With all six brothers killed, each Barrows chest gives seven reward rolls. Every roll has a 1/102 chance of Barrows equipment. For one specific item, that works out to 7/2,448 per chest.

Check target odds and future-chest chances

How the chance is calculated

For one exact item: 7 reward rolls ÷ 102 ÷ 24 items = 7/2,448 per chest. Across multiple chests, the calculator treats each chest opening as independent.

What the calculator covers

Use it for chests where all six brothers were killed. It shows per-chest and cumulative target odds, calculates the chance over a future number of chests, and shows whether an entered result is dry, normal, or lucky. Common rewards, selective brother kills, loot values, and collection log completion need different calculations.

Examples

Ahrim's hood after 1,000 chests

By 1,000 all-six-brothers chests, the expected count is 2.86 Ahrim's hoods. The chance from one chest is 0.29%, with a long-run average of about one Ahrim's hood every 350 chests.

Any equipment after 350 chests

By 350 all-six-brothers chests, the expected total is 24.02 equipment drops. The chance from one chest is 6.66%, with a long-run average of about one equipment piece every 15 chests.
