What is the drop rate for the Plan: Staff of Herding?

I've done an Izual run on Normal about 15 times now and he hasn't dropped it yet.

What is the Staff of Herding plan's drop rate?


Solution 1:

I have read quite a few similar questions on other forums, and according to the majority of the answers it seems that many people get it after 20 tries and most get it after 40 tries. I think the drop rate is somewhere between 2% and 5% (without MF).

Here is an important Note: The "Plan: Staff of Herding" is a legendary item and thus it is affected by Magic Find. If you have a very high MF > 300 % you will get the Plan very often. I tried it 3 times for test purposes and got it 3 times, might be luck though.

Here are some tips for your run:

  • Get level 60 and do it on normal difficulty with MP10
  • Get +% Movement Speed on your boots. You can buy very cheap ones for 1-5k as you are way overpowered for Normal.
  • Use abilities for faster movement and adjust your build for maximum speed. Teleport, Valut, Smoke Screen etc.
  • Kill all champions you find on your way for the +MF.
  • Put on your highest MF gear just before killing Izual.

Solution 2:

Drop rates aren't known yet. I and many others were "lucky" and got it on our first try. The game is still relatively new and it seems even if Blizzard wanted a specific probability for the drop rate of this item that the real life experience would not be the same.

Thus far it seems Blizzard is experimenting with their drop-rate formula/code. Best answer: Random between 1 and 200+ runs. Though that answer sucks, it's 100% accurate and I don't know how someone can be more accurate (as of right now).

If you want a tip on speeding up the process:

  1. Work with a friend to get to Izzy.
  2. One of you leave when you get there
  3. Other kills Izzy

This way the person who left can keep starting a new game to keep letting their friend in to kill Izzy.

There's a helpful guide here.

It's possible that you're getting the drop, but not seeing it. The plans are a common, white item that gets ignored when most people only pick up blues or better. The plans now drop as legendary (brown) as of patch 1.3, which should be easy to pick out.
