Boss loot variance

Pick a boss, set a kill count, and see what the drop table actually pays — expected value, the spread around it, and the odds on every line. Drop rates come from the OSRS Wiki, prices from the live Grand Exchange feed.

Drop table

Every rate and price is editable — change one and the whole page recalculates. Untick a line to leave it out, or fill in a blank rate for a drop the wiki hasn't measured yet.
