Drop rate: 1 in…Kills (or attempts)

After 5,000 kills at 1/5,000, 63.2% of players would have had at least one drop. On average a 1/5,000 drop takes 5,000 kills; half of all players have it by 3,466 kills.

P(at least one drop) = 1 − (1 − 1/rate)^kills.

How pet drops work

Boss pets are untradeable rare drops. Each kill has the same chance of rolling the pet, so the chance of having had it grows with more kills — but no number of kills guarantees one.

Drop chances vary by boss
Each kill is an independent roll
Going very dry is normal luck
Past kills don’t raise the next one’s chance
