I misread this question at first glance, but I’m going to stick with what I thought it said, since that’s a more interesting question. First, here’s the quote:
Vaeflare: While I’ve not been lucky enough to experience it firsthand, Diablo III bosses do indeed have a chance to drop Legendaries and Set items. 🙂
Nice of Vaeflare to cement his “noob” status but perhaps he read the post as I did at my first glance, when I thought the OP was asking about Act Bosses dropping legendaries. But yes, regular bosses can drop legendaries. In fact that’s where I get maybe 2/3 of mine now that I’m playing with max MF, with the other 1/3 coming from white “trash” mobs (who aren’t actually so trashy, as they provide most of your exp and plenty of gold and other loot).
That said, in the first dark months after Diablo III’s release, I might almost have echoed the OP’s question, since from like May-August I only found a handful of orange/green items, most from trash mobs, but even back then I’d seen one or two drop from bosses, or had them drop for friends in MP games.
What I had not seen, until fairly recently, was a legendary drop from one of the supposedly bigger-dropping quest bosses such as the Skeleton King, Magda, Ghom, etc. They’d pop 4 or 5 rares, but never a green or orange. (I’ve since seen this a few times.) I still have not ever personally seen a legendary drop from an Act Boss, and I often tack Azmodan or The Butcher onto the end of an item or key run just to give it a try. Diablo 2 this ain’t.
I know it can happen though, since I’ve heard others report it and I’ve even seen it in video; most recently when Green Pants drop from Azmodan in the 3rd kill in that video about how the Barbarian’s off-hand weapon’s DPS doesn’t matter when using WW.
So the question to you guys; where do you get your legendary and set items?
