Diablo – see the total amount of the crafting materials

If I understand your question, you're asking if you can reset him so that when you start training him again, he'll get a different set of recipes.

Even if you could reset him (which I don't believe you can do), this won't work. My wife and I both got in the beta. I just compared her blacksmith to mine, and except for the fact that I'd trained mine up a little bit further, we had exactly the same recipes. I'm pretty sure the list of recipes you get for him as you train him is fixed. Every time you spend some gold to train him, you unlock a few more recipes. So if you did somehow manage to reset him, you'd just have to work to re-unlock all of the recipes you've already unlocked.

If it is randomized, then it would be one heck of a coincidence that my wife and I unlocked the same set of recipes up though level 2 training.

The only restrictions are these:

• The materials are account bound so they cannot be traded or sold on the auction house
• The materials can only be used to craft the Staff of Herding for Normal difficulty. Crafting the higher grade staves requires that you have the Staff of Herding from the previous difficulty + the plans for the upgraded variant, which can be bought during Act 4 of the difficulty in question.

With this in mind, you should be fine crafting the staff with ingredients taken from multiple characters or difficulties.
