OSRS loot simulator - roll boss and raid drops

Simulate the loot from Old School RuneScape bosses, raids and reward chests over as many kills as you like. The loot simulator rolls each item against its real drop rate - including the rare drop table, tertiary drops and unique reward chests - then totals the haul at live Grand Exchange prices so you can see the expected value of a grind before you start it.

How the loot simulator works

Every monster's drop table is parsed from the Old School RuneScape Wiki: the exact drop quantity and probability of each item, the rare drop table odds, and any tertiary rolls like clue scrolls, pets and unique drops. Each simulated kill rolls those tables the same way the game does, so over a large number of kills the results converge on the true drop rates. Prices are live, so the gp value of your simulated loot reflects the current market.

Frequently asked questions

Is the loot simulator accurate to the real drop rates?

Yes. It uses the published Old School RuneScape drop rates for each monster, including the rare drop table and tertiary drops, and rolls them independently per kill just like the game.

Can I simulate boss and raid drops?

Yes - bosses, raids (Chambers of Xeric, Theatre of Blood and Tombs of Amascut) and their reward chests are all supported, with unique drop odds scaling by points or invocation where the real mechanic does.

How is the value of the loot calculated?

Each dropped item is valued at its live Grand Exchange price and summed, so the total is what the loot would sell for right now.
