Gathering Multiloot Calculator
Model bonus ore and log drops from mining and woodcutting multiloot. Each vein/tree harvest always gives one main resource; multiloot adds a chance for one extra.
How gathering multiloot works
tl;dr — Every harvest gives 1 ore or log. Your mining or woodcutting multiloot % is the chance to proc one additional copy on that same harvest.
Unlike Drop Quantity (exponential, for cards and rare loot), multiloot is a flat percentage for bonus main resources only.
Example: 15 woodcutting multiloot on goak → each chop yields 1 goak log, plus 15% chance of a second log.
Expected per harvest = 1 + (Multiloot % ÷ 100)

Calculator notes
- Vein and tree main drops are 1 in 1 in the cards database — one resource every harvest before multiloot.
- Mining multiloot and woodcutting multiloot are separate stats in-game.
- Combat multiloot (hunter meat, etc.) uses different base rates — not covered on this page.
- Card, pet, and rune odds use Drop Quantity — see the Drop Chance Calculator.
