Drop odds, luck and records

Open a drop tile and you see up to eight lines, one per item that has known odds. A line looks like this:

Item: 1 in 512 from Boss · ~512 kills ≈ 9.4 h at 55/h

If the item can be rolled more than once per kill, it also says (×2 rolls). If Anvil doesn’t know how fast people kill that boss, the hours part is left out.

Luck compares the kills you have done with the kills it should take. If you have the drop in fewer kills than expected, you are spooned. If you have done a lot of kills and still have nothing, you are dry. In between, you are on rate.

Anvil marks you dry or spooned only when it is unusual: about a one in twenty chance or rarer. It shows how many you have against how many were expected, and how far ahead or owed you are.

The Luck tab on the Members page lists the driest and luckiest people in your clan. Plugin posts for rare drops can also carry a luck line, such as a top percentage or how many players would have had it by now.

Drop rates come from the OSRS Wiki and are refreshed every day. Kill rates for the hours come from the Wiki’s money-making guides. Where a rate is a careful estimate, Anvil treats it as one.

If a rate looks wrong, the Wiki is the place to fix it. Anvil picks up the change.

Anvil keeps your best day, week, month and year for skill XP, boss kills and efficient hours. Days are UTC and weeks start on Monday.

Records go back to when Anvil started tracking your account: the first time you open them, Anvil fills them in from your daily history, then keeps them up to date. A record only changes when you beat your old best.

You see your own on your character’s page, under Records. Your clan’s record holders are on Members → Records.

Efficient hours played is how long your gains would take at good training methods, so a fast skill and a slow one can be compared. Efficient hours bossed does the same for kills. The rates come from the OSRS Wiki, and ironman accounts use their own rates.
