Can I farm more than one of each key before crafting my Infernal Machine(s)?
I plan on farming Act 1 for a while, as I've done so much Act 3 farming I'm quite bored with it.
I've added Fields of Misery to my farming path once I get 5 NV stacks, so I can get my first key.
However, once it drops, will I be able to continue farming more Act 1 keys? I want to be able to use 3 Infernal Machines at once, to ensure that I get one of each combination of bosses, but I'm not sure if I can have more than one key at a time.
Yes, you can get multiples of the same key before you craft the Infernal Machine. Keys are stackable, though I'm not sure what the maximum stack size is.
