Drop chance: am I dry?

How likely a drop was within your kill count, and how many kills it takes for a 50%, 90% or 99% chance. Pick a drop from any monster, or type the rate yourself. Boss pets use their kill count threshold.

Each kill is an independent roll. With a pet threshold, the chance is (1 + kills / threshold) / rate, rounded down, up to 10 / rate, as the wiki's Boss pets page describes; normal and hard mode kills count together.
