Take the 2-minute tour ×  At level 60, the Nephalem Valor buff
kicks in. Killing champion packs increase the effect, which
gives a boost to gold and magic find, and increases the number
of drops from bosses.  How many stacks can you get? What causes
you to lose stacks? How much gold find and magic find does each
stack give? How many extra drops from bosses does it give? Is it
any boss, or only Inferno bosses?  share|improve this question
Details are going to be scarce until people actually hit level
60, but here are a few facts: It works as soon as you're level
60, regardless of difficulty. Changing your skills will reset
the buff. –  StrixVaria May 14 '12 at 23:50 add comment  4
