The Fractured Archive Loot Simulator

Loot simulator

Pick a boss, raid or reward chest and a number of runs to roll its loot - what you'd get and what it's worth at live GE prices.

Completions

Standard chests only: the wiki has no rate yet for the uniques or the pet, so none are rolled.

The Fractured Archive uniques

From most to least common, as the wiki ranks them. No drop rate has been published for any of them (or for the pet, Orion), nor how your contribution points and party size change the chance, so the simulator above doesn't roll them: every completion there is a standard chest.

Rondache Most common · rate not published 124.22m
Zorya's tome (uncharged) 2nd most common, joint · rate not published 164.72m
Horn of Bran 2nd most common, joint · rate not published 1.24b
Ascension crossbows 3rd most common · rate not published 742.05m
Obligator (uncharged) Rarest · rate not published 3.64b

Expected loot · average haul from 1,000 standard chests, at live GE prices

This is the mathematical average, not a roll: each item's quantity is its drop rate times 1,000 completions. That works out at about 356,952 gp per standard chest.

How the Fractured Archive chest works

With no unique, your chest rolls the standard table 3 times. Each roll has a 1/51 chance to give 5 times the quantity below. The rates are what the Drop Log Project recorded over 14,487 chests, so treat them as close estimates. On top of that each chest can hold a tertiary: Archivist's folio (1/20), Fragment of whispering wind (1/80), Fragment of deep water (1/80), Fragment of living earth (1/80), Fragment of burning fire (1/80) and Clue scroll (elite) (rate not published). The elemental fragments have a duplicate protection whose rule isn't public, so each is counted at a flat rate here. A team that performs badly enough gets only a cabbage, which isn't simulated.

Simulate The Fractured Archive chests in Old School RuneScape over as many completions as you like. Without a unique, the chest rolls its standard table 3 times, and each roll has a 1 in 51 chance to pay out 5 times the usual amount. At live Grand Exchange prices a standard chest is worth about 356,952 gp on average. The uniques are Rondache, Zorya's tome, Horn of Bran, Ascension crossbows and Obligator, from most to least common, but no drop rate for them has been published yet, so the simulator rolls standard chests only and never invents a purple chance.

The Fractured Archive loot - frequently asked questions

What are the uniques from The Fractured Archive?

Rondache, Zorya's tome, Horn of Bran, Ascension crossbows and Obligator, in order from most to least common (Zorya's tome and the Horn of Bran are about as common as each other). The pet is Orion. The most valuable right now is the Obligator, at about 3,638,349,710 gp.

What is the purple chance in The Fractured Archive?

It hasn't been published. Jagex has said a unique follows your contribution points, and that both bosses at each fork award the same points, so the path you take doesn't change it. How the size of your party (one to eight players) changes it hasn't been published either. Until the rate is known, this page doesn't estimate one.

How much is a Fractured Archive chest worth?

A standard chest (no unique) averages about 356,952 gp at current Grand Exchange prices, from 3 rolls on its table.

Is this loot simulator accurate?

For the standard chest, yes: it uses the rates the wiki lists from the Drop Log Project's 14,487 recorded chests, so they are close but not exact. Uniques, the pet and the elite clue aren't rolled because their rates aren't published.
